Best ResponseYou've already chosen the best response.2\[(x+a)(x+b)\\ = x(x+b)+a(x+b)\\ = x^2+bx+ax+ab\\ =x^2+(a+b)x+ab \]

Best ResponseYou've already chosen the best response.2but then we also need to know all combinations of 6 and what sign patterns we need to make this true.

Best ResponseYou've already chosen the best response.2that's the longest reply I've ever seen so far... xD anyway... not only do we need all combinations of 6, but the sign patterns are important too because based on what we are given, the middle number is negative.
