Find the difference of the polynomials below. Write your answer in descending order.
(x^3 + 2x^2 + 5x + 7)  (3x^3  2.5x^2 + 5x + 5)

I will start you out:
2x^3+.5x^2 ....+2 
in the second part of parenthesis distribute the negative(multiply the negative by everything in the parenthesis) and then combine like terms

your answer will be 2x^3+4.5x^210x+2
