To find:

To determine the values of a, b, and c that are needed in order to use the Quadratic Formula

Explanation

Consider the following equation,

5x2=90âˆ’2xâ‡’5x2+2xâˆ’90=0.

The general form of the quadratic equation is given below,

ax2+bx+c=0

Where a is the number multiplied by x2, b is the number multiplied by x, and c is the constant term.
