Question

Use the quadratic formula to solve for the roots in the following equation.

Answer 1

First lets combine terms.

4x 2 + 5x + 2 = 2x 2 + 7x – 1 subtract the left side from right side

(4x 2- 2x 2) + (5x - 7x) + (2 + 1)=0 then combining
2x 2 - 2x + 3 =0  now we can use the quadratic formula


a=2,   b=-2   c=3
