ok let me show the general idea then we can do this specific problem starting with a quadratic \[x^2 + bx + c\] it can be factored to look like this \[(x +p)(x+q)\] only if \[p + q = b\] and \[p*q = c\] So the goal is always to find 2 numbers which multiply to get "c" and add to get "b"

now think of 2 numbers that multiply together to get 11

They want me to do a diamond problem and check it. It's the common core system.|dw:1402360756368:dw|
