For this problem: -------- ok this is what i know 6x^2-54 you can't factor these things out so what do i ?? thank you --------- there is a factor of 6 common to each term so: 6(x^2 - 9) In the parentheses you have the difference between two squares, which factors: 6(x + 3)(x - 3) Hope that helps...
