Write Expression: Write down the expression to be factored.The expression given is (x−9)+(x−9)2. We need to factor this expression completely.
Recognize Common Term: Recognize the common term in both parts of the expression.We can see that (x−9) is a common term in both (x−9) and (x−9)2.
Factor Out: Factor out the common term (x−9).We can factor (x−9) out of the expression, which gives us (x−9)(1+(x−9)).
Simplify Expression: Simplify the factored expression.The expression (x−9)(1+(x−9)) simplifies to (x−9)(x−9+1) or (x−9)(x−8).
Check Further Factoring: Check for any further factoring. The expression (x−9)(x−8) cannot be factored further since both (x−9) and (x−8) are linear terms with no common factors.
