Question

Find the complete factored form of thepolynomial:9ab5 - 6ab4

Answer 1

9ab5 - 6ab4 = 3 . 3 . a . b . 5 - 3 . 2 . a . b . 4

Now we can look for the common factors: 3 , a, and b. Then we put these factors in evidence:

`3ab((9ab5)/(3ab)-(6ab4)/(3ab))=3ab(3\cdot5-2\cdot4)=3ab(15-8)=3ab7`

Therefore, the complete factored form of this polynomial is 3ab7.
