When we add or subtract polynomials, there may be parentheses that show the groupings of each polynomial, but don't actually mean multiplication, like we're used to. To add or subtract, combine "like terms"- that is, terms with the same variables with the same exponents. One strategy is to line up the polynomials vertically with "like terms" stacked on top of each other. You could also draw pictures to represent polynomials, with different shape rectangles to represent x squared terms, x terms, or constants.
