Best ResponseYou've already chosen the best response.1what we have done so far looks like this right? \[2x^3 8x^2 9x +36\] \[(2x^38x^2)+(9x+36)\] \[2x^2(x4)+9(x+4)\]

Best ResponseYou've already chosen the best response.1how do we get: (x4) to equal (x+4) ? what can we factor out of ...lets say the one on the right?

amistre64

Best ResponseYou've already chosen the best response.1close, real close; but lets try a (1) \[(x+4)\iff 1(x4)\]

Best ResponseYou've already chosen the best response.1\[2x^2(x−4)−9(x−4)\] what do these have in common that we can factor out? think of it as: \[2x^2(A)9(A)\]
