Question

Solve:
-2x^2 + 3x - 7

Answer 1

Set the polynomial equal to zero, and then multiply both sides by -1 in order to give x^2 a positive coefficient. Now you have 2x^2 - 3x + 7 = 0, which cannot be factored since no two factors of 7 can add up to -3 when one of them is multiplied by 2. In this case, you will have to use the quadratic formula with the form ax^2 + bx + c =0.
