Which equations are incomplete quadratic equations? a) x 2 − 4 = 0 d) 2 x 2 − 4 = 2 x 2 + 8 x b) x 2 − 4 x = 0 e) x 2 = 9 4 c) 3 x 2 = 2 x f) x 2 − 2 x − 3 = 0

To determine

(a)

To find:

To find the following equation x24=0 are quadratic.

Explanation

Consider the following equation,

x24=0.

The general form of the incomplete quadratic equation is given below,

ax2+c=0

Where a is the number multiplied by x2 and c is the constant term. Highest power of quadratic equation is 2.

Compare the given equation with general equation to get the following,

ax2+c=0

To determine

(b)

To find:

To find the following equation x24x=0 are quadratic.

To determine

(c)

To find:

To find the following equation 3x2=2x are quadratic.

To determine

(d)

To find:

To find the following equation 2x24=2x2+8x are quadratic.

To determine

(e)

To find:

To find the following equation x2=94 are quadratic.

To determine

(f)

To find:
