Factoring and Simplifying the Expression (x+2)² - 5(x+2)
This expression can be simplified and factored using algebraic techniques. Let's break down the process step by step.
Understanding the Expression
The expression (x+2)² - 5(x+2) involves:
- A squared term: (x+2)² represents the product of (x+2) multiplied by itself.
- A linear term: -5(x+2) is a simple multiplication of -5 and (x+2).
Factoring by Grouping
We can simplify the expression by factoring out the common factor (x+2):
- Identify the common factor: Notice that both terms in the expression contain (x+2).
- Factor out the common factor:
- (x+2)² = (x+2)(x+2)
- -5(x+2) = -5(x+2)
- Rewrite the expression: (x+2)(x+2) - 5(x+2) = (x+2)[(x+2) - 5]
Simplifying the Expression
Now we can simplify the expression inside the brackets:
- (x+2)[(x+2) - 5] = (x+2)(x - 3)
Final Result
The simplified and factored form of the expression (x+2)² - 5(x+2) is (x+2)(x-3).
