If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that Add up to 5 Multiply together to get 4 Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1)(x+4)
Given a quadratic with leading coefficient equaling 1, the factors are found using factors of the last number that add up to be the middle term's coefficient. The factors are then written as (x+m)(x+n), where m*n equals the last number in the quadratic and m+n equals the middle ...
Looking at the coefficients of this quadratic expression, I have a = 2, b = 1, and c = −6, so ac = (2)(−6) = −12. This tells me that I need to find factors of −12 that add up to +1. The factor pairs for 12 (not considering signs) are 1 and 12, 2 and 6...
