The answer to 0 equals x2 plus x-20 using the quadratic formula?
You do not need the quadratic formula, since this can easily be factored in to linear factors.x2 + x - 20 = (x - 4)(x + 5), thus, x = 4 or 5.But, using the quadratic formula:(-b +- sqrt(b2 - 4ac))/2a = (-1 +- sqrt(1 + 80))/2(-1 + 9)/2 = 4(-1 - 9)/2 = -5
