Question

Factor out the greatest common factor
-5x^2 - 5x^3 - 15x^4

Answer 1

Our answer is
`-5x^(2) (3x^(2) +x+1)`

Our greatest common factor, or GCF, is
`-5x^(2)`, so when we factor is out, our divide each term by
`-5x^(2)`, we get our answer. To check this, we can multiply the
`-5x^(2)` back across the parenthesis and see if we get the same result as our initial question.

Hope this helped! :))
