Math Problem Statement
Solution
The given expression is:
To simplify this, we rationalize the denominator by multiplying both numerator and denominator by the conjugate of the denominator, . Here's the process:
Step 1: Multiply numerator and denominator by the conjugate
Step 2: Simplify the denominator
Using the difference of squares formula:
So, the denominator becomes .
Step 3: Expand the numerator
Simplify term by term:
Adding these, the numerator becomes:
Step 4: Write the simplified expression
Thus, the final simplified expression is:
