Best ResponseYou've already chosen the best response.0try to factor out (x+1), (x+2)...up to 6 if that works you'll be left with a quadratic

Best ResponseYou've already chosen the best response.0actually you can factor out (x+1) there are different ways of doing this (x+1)(x^2 +bx +6) = x^34x^2+x+6 we have to find b, if b is an integer it works x^2+bx^2 = 4x^2 (b+1)x^2 = 4x^2 b+1 = 4 b = 5
