(0,-6) and (0,3) because the x intercept is when y=0 and if you want y to equal 0 one of the 2 parenthesis's values should equal 0 there are 2 answers because even if one of the parenthesis equals 0 the other one that is multiplied by it no matter what the value of that is equals 0. For example take (x+3)(x-4) one way to make this 0 would be for x to equal -3 or +4.
