    |dw:1433683785195:dw| You need to expand the brackets by multiplying the coefficient ( number and x infant) with each element in the brackets and adding together in the first step. Try it.

    8(x^2-1)+3x(x+2) When you distribute the 8 by the first set of parentheses, you will get 2 unlike terms, one in x^2 and one constant term. When you distribute the 3x by the second set of parentheses, you will get two unlike terms, one in x^2 and one in x. How many total unlike terms do you have after distributing twice?
