Using the factoring method, solve for the roots of the quadratic equation. Be sure to place your equation in standard form before factoring. 5x^2-x=-16x
5x^2 - x = -16x 5x^2 - x + 16x = 0 5x^2 + 15x = 0 5x(x + 3) = 0 x = 0 or x = -3

5x^2 - x = -16x
5x^2 - x + 16x = 0

x^2 + 8x - 48 = 0
x^2 + 8x + 16 = 48 + 16
(x + 4)^2 = 64
x + 4 = 8 or x + 4 = -8
x = 4 or x = -12
