Math Problem Statement
Solution
The expression given is:
To simplify this, we will first factor both the numerator and the denominator.
Step 1: Factor the numerator
The numerator is . We need to find two numbers that multiply to (the constant term) and add to (the coefficient of ).
Those two numbers are and , so we can factor the numerator as:
Step 2: Factor the denominator
The denominator is . We need to find two numbers that multiply to and add to .
Those two numbers are and , so we can factor the denominator as:
Step 3: Simplify the expression
Now that both the numerator and denominator are factored, we have:
We can cancel out the common factor in both the numerator and denominator (as long as ):
So, the simplified expression is:
