## Algebra Formulas For Class 10

An important algebra formula introduced in class 10 is the quadratic formula. The general form of the quadratic equation is ax2 + bx + c = 0, and there are two methods of solving this quadratic equation. The first method is to solve the quadratic equation by the algebraic method, and the second method is to solve through the use of the quadratic formula. The below formula is helpful to quickly find the values of the variable x with the least number of steps.

In the above expression, the value b2 – 4ac is called the determinant and is useful to find the nature of the roots of the given equation. Based on the value of the determinant, the three types of roots are given below.

- If b2 – 4ac > 0, then the quadratic equation has two
**distinct real roots**. - If b2 – 4ac = 0, then the quadratic equation has two
**equal real roots**. - If b2 – 4ac < 0, then the quadratic equation has two
**imaginary roots**.

## Example: Y = 2x + 1 Is A Linear Equation:

The graph of **y = 2x+1** is a straight line

- When x increases, y increases
**twice as fast**, so we need 2x - When x is 0, y is already 1. So +1 is also needed
- And so: y = 2x + 1

Here are some example values:

x | |
---|---|

y = 2 × + 1 = -1 | |

0 | y = 2 × 0 + 1 = 1 |

1 | y = 2 × 1 + 1 = 3 |

2 | y = 2 × 2 + 1 = 5 |

Check for yourself that those points are part of the line above!

## Notation Language And Rigor

Most of the mathematical notation in use today was not invented until the 16th century. Before that, mathematics was written out in words, limiting mathematical discovery.Euler was responsible for many of the notations in use today. Modern notation makes mathematics much easier for the professional, but beginners often find it daunting. According to Barbara Oakley, this can be attributed to the fact that mathematical ideas are both more *abstract* and more *encrypted* than those of natural language. Unlike natural language, where people can often equate a word with the physical object it corresponds to, mathematical symbols are abstract, lacking any physical analog. Mathematical symbols are also more highly encrypted than regular words, meaning a single symbol can encode a number of different operations or ideas.

## Inspiration Pure And Applied Mathematics And Aesthetics

Mathematics arises from many different kinds of problems. At first these were found in commerce, land measurement, architecture and later astronomy today, all sciences pose problems studied by mathematicians, and many problems arise within mathematics itself. For example, the physicistRichard Feynman invented the path integral formulation of quantum mechanics using a combination of mathematical reasoning and physical insight, and today’s string theory, a still-developing scientific theory which attempts to unify the four fundamental forces of nature, continues to inspire new mathematics.

Some mathematics is relevant only in the area that inspired it, and is applied to solve further problems in that area. But often mathematics inspired by one area proves useful in many areas, and joins the general stock of mathematical concepts. A distinction is often made between pure mathematics and applied mathematics. However pure mathematics topics often turn out to have applications, e.g. number theory in cryptography.

As in most areas of study, the explosion of knowledge in the scientific age has led to specialization: there are now hundreds of specialized areas in mathematics and the latest Mathematics Subject Classification runs to 46 pages. Several areas of applied mathematics have merged with related traditions outside of mathematics and become disciplines in their own right, including statistics, operations research, and computer science.

## Symbols That Do Not Belong To Formulas

In this section, the symbols that are listed are used as some sorts of punctuation marks in mathematical reasoning, or as abbreviations of English phrases. They are generally not used inside a formula. Some were used in classical logic for indicating the logical dependence between sentences written in plain English. Except for the first two, they are normally not used in printed mathematical texts since, for readability, it is generally recommended to have at least one word between two formulas. However, they are still used on a black board for indicating relationships between formulas.

- ,
- Used for marking the end of a proof and separating it from the current text. The initialismQ.E.D. or QED is often used for the same purpose, either in its upper-case form or in lower case.
- Bourbaki dangerous bend symbol: Sometimes used in the margin to forewarn readers against serious errors, where they risk falling, or to mark a passage that is tricky on a first reading because of an especially subtle argument.
- Abbreviation of “therefore”. Placed between two assertions, it means that the first one implies the second one. For example: “All humans are mortal, and Socrates is a human. Socrates is mortal.”
- Abbreviation of “because” or “since”. Placed between two assertions, it means that the first one is implied by the second one. For example: “11 is prime it has no positive integer factors other than itself and one.”

## List Of Mathematical Symbols By Subject

The following **list of mathematical symbols by subject** features a selection of the most common symbols used in modern mathematical notation within formulas, grouped by mathematical topic. As it is impossible to know if a complete list existing today of all symbols used in history is a representation of all ever used in history, as this would necessitate knowing if extant records are of all usages, only those symbols which occur often in mathematics or mathematics education are included. Many of the characters are standardized, for example in DIN 1302 *General mathematical symbols* or DIN EN ISO 80000-2 *Quantities and units Part 2: Mathematical signs for science and technology*.

The following list is largely limited to non-alphanumeric characters. It is divided by areas of mathematics and grouped within sub-regions. Some symbols have a different meaning depending on the context and appear accordingly several times in the list. Further information on the symbols and their meaning can also be found in the respective linked articles.

This is part of a series on common misconceptions.

True or False?\frac\right)} = \frac\right)}. c=a.

**Why some people say it’s true:**Just like with multiplication, the order that you choose to evaluate the two division operations doesn’t matter.

**Why some people say it’s false:**It’s almost never true. Maybe there are a few very special cases for choosing a c so that it’s true.

\frac\right)} \neq \frac\right)} c=a. Consider the following example:

Does \frac\right)} = \frac\right)} 2=36?

\frac\right)} = \frac = 3. 2=26=3.

\frac\right)} = \frac =12. 36=336=12.

3=12. Therefore, the given equation is false.

\frac\right)} = \frac\right)} c=a:c all equal 1, then this equation is true. But there are many other examples.

If \frac\right)} = \frac\right)} c=a, then by cross-multiplying, we can simplify to

a c . \begin\frac \times \frac & = a \times c\\\frac & = a \times c\\ \frac & = a \times c\\ \frac & = c.\end ba×cbb×ca×bcac1=a×c=a×c=a×c=c.

The only two values that satisfy the equation 1 1 c=-1 c=1. Therefore, the set of all cases when the original equation is true are those where c 1 c = 1 \text -1 c=1 or 1. The other two variables can take on any values, so long as c

\frac\right)} = \frac\right)} 1=36?

\frac\right)} = \frac = -6. 1=16=6.

\frac\right)} = \frac =-6. 36=636=6.
