Question

I've been doing this for a good hour...

Factor: 5x^(2)(x+3)^(-4)-10x(x+3)^(-7)
or http://www.wolframalpha.com/input/?i=5x^%282%29%28x%2B3%29^%28-4%29-10x%28x%2B3%29^%28-7%29

I'd love some help!

Answer 1

\[5x ^{2}(x+3)^{-4}-10x(x+3)^{-7}\] may be factored as such:

\[5x(x+3)^{-7}(x(x+3)^{3}-2)\]

now you can justt expand and simplify

Answer 2

ok, thanks!
