I think you should start by using the quadratic formula, though I think there might be a better way

take the factors of 7 and 5 and mess with them to get all the possible b's
the only factors of 7 are 1 and 7 and the only factors of 5 are 1 and 5
so how would i list that?
the answers are 12, -12, -2 and 2
I think. check if that's right
12, -12, 36, -36
36 doesn't work
try factoring it
7x^2 + 35x + x + 5
7x(x+5) + 1(x+5)
