Question

Factor the trinomial over the integers. Show your solution, and say what type of reasoning you used.
76x2 − 7x − 3

Answer 1

Well, when we have a quadratic in the form of ax^2 + bx + c = 0
1. First we need to multiply A and C. In this case, A is 76 and C is -3. The signs are important when we do this. After we multiply those two
2. We find two factors of AC that will add up to equal B. So whichever two numbers that we find that multiply to equal AC, those same two numbers must also add up to equal B, which is -7 in this case.
These are probably thetwo most important steps. Think we can do that part and then continue from there?
