factor each of a, b, and c to see what factor them. That will give you your answer, because if the factors of any or all of a, b, and/or c are the ones in the problem, then that selection is also a factor of P.

For the first one, (x+1) (x+2)

Good!, so 1) is a factor of P. And just check 2) and 3).

For the second one , (x+1) (x-1)

Good! So, 2) is a factor. Hint: if 2) works, then 3) automatically works because there is no selection for only 1) and 2).

For the third one, (x+2) (x-1)
