To do this we do something called factoring. In this case, we would multiply x by 3x, and x by -5. Then we would multiply 3 by 3x, and 3 by -5. So, let's do it: x*3x = 3x^2 x*(-5) = -5x 3*(3x) = 9x 3*(-5) = -15 Therefore, the final answer would like this (after adding the like terms: -5x+9x): 3x^2 + 4x - 15
