2. Relevant equations

3. The attempt at a solution

This is a problem I have for a homework assignment. I punched it in on Wolfram, and there is the answer it gives. I can't figure out how to solve this thing. I tried multiplying by the conjugate radicals and simplifying, tried factoring out the highest power of x, but nothing seems to work.
