The factored form is

#### Explanation:

You have to factor by grouping:

#### Answer:

This factors to

#### Explanation:

Starting with the left-hand side, we see

Based on the middle terms, I would believe that the factors are uneven (NOT

Now, expand the above and back-substitute the values of a & b from the starting equation:

Comparing the middle coefficients, it would seem that b=-2 and a=4. This is confirmed with the final term

Therefore, the factored solution is:
