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:
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^2-10x+2
