• In Step 1 because the expression inside the parentheses needs to have a sum of -11x, not 11x.

• In Step 2 because the sign on x should be negative and the sign on 2 should be positive.

• In Step 3 because there is no need to multiply (x-2) by 1.

• In Step 4 because (x-2) should be written first.

Identify each expression that is a factor of this polynomial:

• x - 1

• 3x - 2

• 3x + 1

• 3

• x + 1
