Sandra graphed the system of equations that can be used to solve x^3-2x^2-11x+12=x^3-13x-12 what are the roots of the polynomial equation? a.) –12, 12 b.) –4, 3 c.) –3, 4 d.) –1, 1

First you need to solve the equation for x so it would become -2x^2+2x+24=0, when you factor it out it becomes -2(x^2-x-12)After factoring the inside it becomes -2(x-4)(x+3). Now (x-4) equals to 0 and (x+3) equals to 0 after solving for x you get the roots 4,-3
