Solve x^2x12=0, Microsoft Math Solver

To solve the equation, factor x2 x 12 using formula x2 + (a +b)x+ ab = (x+a)(x+ b). To find a and b, set up a system to be solved. a+b=1 ab=12. a + b = 1 ab = 12. Since ab is negative, a and b have the opposite signs. Since a+b is negative, the negative number has greater absolute value than the positive.
