Question

Factor the GCF out of the following expression to create a multiplication problem.

-72n^5 +81n³

Answer 1

Answer:For 9n^3: (9n^3) * (-8n^2+9)

For -9n^3: (-9n^3) * (8n^2-9)

Explanation:

The GCF is the greatest common factor.

The great common factor between 72 and 81 is 9 as 72=9*8 and 81=9*9

the GCF between n^5 and n^3=n^3.

SO the GCF is 9n^3.

But I would like to keep that leading coefficient positive, so i will factor -9n^3. It doesn't matter which one you choose, ill do both so u will have both ready.

For 9n^3: (9n^3) * (-8n^2+9)

For -9n^3: (-9n^3) * (8n^2-9)
