Maximum And Minimum Values In Restricted Domain

Case 1: -b/2a

f =

Case 2: -b/2a

Example 1: Find the maximum or minimum value of quadratic expression -42 + 2.

Solution:

Since the value of a is negative, therefore the given quadratic equation will have a maximum value. Hence, the maximum value of the quadratic equation -42 + 2 is 2.

Example 2: Find the minimum and maximum values of quadratic expression f = x2 12x + 11.

Solution:

Since a > 0, the maximum and minimum values of a quadratic expression is given by:

Therefore, the minimum value of f is:

-/4 at x = – = -25 at x = 6.

The maximum value of f is infinity.

Therefore, the range of the given quadratic equation is [- 25, ).

Example 3: Find the minimum value of equation y = /?

Solution:

f will have minimum value at x = -b/2a

i.e. at x = -3/4.

the minimum value of quadratic equation f = -D/4a = -/8 = 39/8.

Example 4: Find the range of function f = /, if x is real.

Solution:

Let y = /

2x2y + 3xy + 6y = x + 2

2x2y + x + 6y -2 = x + 2

Now, discriminant = 2 4. 0

9y2 + 1 6y 48y2 + 16y 0

39y2 10y 1 0

39y2 13y + 3y 1 0

What Is Quadratic Equation

Quadratic equations are the polynomial equations of degree 2 in one variable of type f = ax2 + bx + c = 0 where a, b, c, R and a 0. It is the general form of a quadratic equation where a is called the leading coefficient and c is called the absolute term of f . The values of x satisfying the quadratic equation are the roots of the quadratic equation .

The quadratic equation will always have two roots. The nature of roots may be either real or imaginary.

A quadratic polynomial, when equated to zero, becomes a quadratic equation. The values of x satisfying the equation are called the roots of the quadratic equation.

General from: ax2 + bx + c = 0

Examples: 3×2 + x + 5 = 0, -x2 + 7x + 5 = 0, x2 + x = 0.

Quadratic Equations Having Common Roots

Let be the common root of quadratic equations a1x2 + b1x + c1 = 0 and a2x2 + b2x + c2 = 0. This implies that a12 + b1 + c1 = 0 and a22 + b2 + c2 = 0.

Now, Solving for 2 and we will get:

2/ = -/ = 1/

Therefore, 2 = / . . . . . . . . . . . . . . . .

And, = / . . . . . . . . . . . . . . . .

On squaring equation and equating it with equation we get:

/ = 2

Hence, it is the required condition for quadratic equations having one common root.

If both the roots of quadratic equations a1x2 + b1x + c1 = 0 and a2x2 + b2x + c2 = 0 are common then:

a1/a2 = b1/b2 = c1/c2

If is a repeated root, i.e., the two roots are , of the equation f = 0, then will be a root of the derived equation.

f = 0 where f = df/dx

If is a repeated root common in f = 0 and = 0, then is a common root both in f = 0 and = 0.

How To Solve Biquadratic Equations

Mr. Camire

Biquadratic equations can be easily solved by converting them into quadratic equations i.e. by replacing the variable z with x2.

Example: Find the zeroes of a biquadratic equation x4 3×2 + 2 = 0.

Solution:

Given x4 3×2 + 2 = 0

On substituting x2 = z in the given equation we get,

z2 3z + 2 = 0

z2 2z z + 2 = 0

z -1 = 0

z = 1 and z = 2

Hence, x = ±1 and x = ±2 .

Maximum And Minimum Value Of Quadratic Equation

Conditions for Minimum and Maximum Value of Quadratic Equation

To find the minimum value of a quadratic equation we need to understand the nature of the graph of these equations for different values of a. The graph of the quadratic equation f = ax2 + bx + c will be either concave upwards or concave downwards respectively.

When the graph is concave upwards then its vertex determines the minimum value of a quadratic function f and when it is concave downwards, its vertex determines the maximum values of a quadratic function f.
