Best ResponseYou've already chosen the best response.0Ive expanded it and tried to solve it but my answer is not a choice on my homework

Best ResponseYou've already chosen the best response.1what did you get as the answer? you may have made a simple math error somewhere

Best ResponseYou've already chosen the best response.0i think the problem is my division after i distribute and cancel out like terms i get (6xh+3h^2+h)/h i get 6x +8h at the end

Best ResponseYou've already chosen the best response.1not quite, h should not be in the final answer at all. let's start from the beginning, ok?

Best ResponseYou've already chosen the best response.0okay so then it would be [3(x^2 + 2xh +h^2 ) + x+h 3x^2 x]/h

Best ResponseYou've already chosen the best response.0i have a question does 3 not distribute to h^2 = 3h^2 ?

Best ResponseYou've already chosen the best response.1dw:1443578317416:dw (and I made a small mistake earlier, h should be in the answer. I was thinking of derivatives for some reason)

Best ResponseYou've already chosen the best response.1now, we factor out h from the numeratordw:1443578421397:dw

Best ResponseYou've already chosen the best response.0yeah this is actually trying to solve for a derivative using [f (x+h) f(x)] / [(x+h)x]

Best ResponseYou've already chosen the best response.1right, so if we're going for a derivative, all we need to do now is set h = 0

Best ResponseYou've already chosen the best response.0ohh so i have to factor out the 'h' okay and then the 0
