**Note: I think you meant x squared. That's why I changed the problem.
------------------------------------------------
1st.) We need to find what will give us 9 when we multiply & will also give us 6 when we add those two numbers together.
I like to look at it like this:
[_] + [_] = 6
[_] * [_] = 9
We know only 1*9=9 and 3*3=9 so from knowing that we can fill in the boxes:
3+3=6
3*3=9
---------------------------------
2nd.) Use the information from above-
