To find the zeros of this equation you need to first set it equal to zero 2x2 + 16x - 9 = 0 But since you can't FOIL this equation you need to move the non-variable number over 2x2 +16x = 9 Now solve for x by pulling an x out of the equation x(2x + 16) = 9 x = 9 2x +16 = 9 2x = -7 x = -7/2 So your zeros would be at x = 9, and -7/2
