Question

Factor the polynomial by its greatest common monomial factor. 3b^5 + 15b^4-18b^7

Answer 1

-3b^4 (6b^3 -b-5)

Explanation:

Answer 2

-3b^4 (6b^3 -b-5)

Explanation:

Each term is divisible by 3b^4 so we can factor this out

3b^5 + 15b^4-18b^7

3b^4( b+5 -6b^3)

Rewriting the inside term

3b^4 (-6b^3 +b+5)

We can factor out a negative

-3b^4 (6b^3 -b-5)
