Sorry im sorry the 6a was just 6x^2

My answer still is 13x^3-6x^2-x

but it reads on the book 13x^3-x

And i said the same thing about it would have to be + 3x^2 for the answer to be 13x^3-x

Well my class is tommorrow so i am going to tell this to my teacher. - Aug 9th 2011, 09:59 AMSironRe: Where did I go wrong?
