Do u know factorization???

Answer 2

Ok. Thanks for posting :3

Here's the steps you should follow and the answer.

The 1st terms are 1 and 3.
There are no minus signs, so it's
(3x + a)*(x + b)
a and b can be:
1 and 36 (this won't work, 36 is too much, >31)
2 and 18


3 and 12
4 and 9
6 and 6
Either a or b has to be an odd number, they can't both be even since 31 is odd.
That leaves:
3 and 12
4 and 9
Answer -> -> -> -> -> -> (3x + 4) * (x + 9)
