Math Problem Statement
Solution
The problem shown in the image is to simplify the expression:
Let's break it down step by step:
Step 1: Factor the numerator and denominator.
- Numerator: can be factored by taking out the common factor of :
- Denominator: is a difference of squares, which can be factored as:
Step 2: Write the expression in its factored form.
Step 3: Simplify by canceling common factors.
Since appears in both the numerator and the denominator, we can cancel it out (as long as , which means ):
Final Simplified Expression:
This is the fully simplified form of the given expression.
