Factor these:

8x^3-125

81x^-625

18x^3+63x^2-50x-175

x^4-11x^2+18

I'm so lost!

differece of cubes

differece of cubes

9x^2(2x+7)-25(2x+7) then gather the common factor, to (2x+7)(9x^2-25), and now the second term is a differece of squares, so It can be factored.

Last

(x^2-9)(x^2-2) both of these terms are difference of squares. (last term (x-sqrt2)(x+sqrt2)
