You can put this solution on YOUR website! DISCLAIMER
There may be a procedure that you were supposedly taught, but I would not know about it.
If is to be the product of two factors,
both factor must include a term on (so we could get terms with and a term with too),
and just one factor must include a term in (so we could get twems in , but no term in ).
Let's try . -->
For the expressions on the left and the right to be equivalent, all four coefficients must match: and
The way I would look for answers would be setting up a tic-tac-toe grid: My first guesses as common factors for each column are and . --> but --> does not agree
However, If I change my guess to , I get and solutions that agree with the ones from : -->
So the solution is or
