$\"\"$

The expression is $\"\"$ .

A polynomial can be factored by grouping:

$\"\"$ (Group terms with common factors )

Find the GCF of each terms.

$\"\"$ (Circle common factors)

GCF of $\"\"$ is r.

$\"\"$ (Circle common factors)

GCF of $\"\"$ is 9. $\"\"$

Write each term as the product of the GCF and the remaining factors.Use the Distributive property to factor out the GCF.

$\"\"$ (Rewrite each term using the GCF)

$\"\"$ (Apply distributive property: $\"\"$ )

$\"\"$ . (Apply distributive property: $\"\"$ ) $\"\"$

The factored form of $\"\"$ is $\"\"$ .
