Bonus Knowledge
To simplify the expression
, we start by factoring the denominators.
The first denominator,
, can be factored using the difference of squares:
The second denominator,
, is a perfect square:
Now, we rewrite the original expression with the factored denominators:
Next, we will find a common denominator to combine the fractions. The common denominator is
.
Now, we rewrite each fraction with the common denominator:
- The first fraction:
- The second fraction:
Now we put these together:
Now, let’s simplify the numerator:
Expanding
:
Now we combine that with the second part:
Now, the overall expression simplifies to:
Thus, the final simplified expression is:
