Factor the Denominators:

For , we can look for factors using the Rational Root Theorem or by polynomial long division. By trying possible rational roots, we find is a root, which gives us

Thus,

For , we also find is a root, leading to

So,

Rewrite the Original Expression:

Now we can rewrite the expression as:

Finding a Common Denominator:

The common denominator is .

Rewrite each fraction to have this common denominator:

Combine the Numerators:

Simplify the Numerator:

Expanding the first term:

Expanding the second term:

Now combine:

Final Expression:

We now have

Factoring from the numerator:
