ANSWER


Step-by-step explanation
Given:

Determine the GCF of all the expression's terms
3: 1, 3
9: 1, 3, 9
36: 1, 2, 3, 4, 6, 9, 12, 18, 36
81: 1, 3, 9, 27, 81
90: 1, 3, 9, 10
Part 1:
The GCF = 3x
Then, to the left of a set of parenthesis, write the GCF: 3x( )
After that, divide each term in the original equation by the GCF (3x) and put it in parenthesis.
That is:

So you have:

Part 2:
The GCF = 3x^2

Hence, you have:
