    that is the problem. people don't know what like terms are and when you post a link they are mostly aren't willing to read it, even though all you got to do is to look at it. I will still attempt to post a link that explains what link terms are. http://www.mathsisfun.com/algebra/like-terms.html

    So this: \[6x^3 + 7x^2 - x + -5\] Would that be it?

    Just to put them here, the answer options are: A. 6x^3 + 7x^2 - x - 5 B. -6x^3 + 7x^2 - x + 1 C. -x^3 - x - 5 D. x^2 - x +1
