Find the difference of (−5x2 − 4x3 − 3) − (9x3 + 3x − 8x2). Be sure to show all of your work in a neat and organized fashion.
Use the ^ (shift 6) symbol to show an exponent. For example, x squared can be written as x^2.

Best ResponseYou've already chosen the best response.0yes your answer is right but your method is fishy.. any go on :) i would say 5x^28x^2 = 5x^2+8x^2=3x^2

Best ResponseYou've already chosen the best response.0lol, correct..not the same terms.. so your answer would be all the stuff together.. i'll give you a start: 3x^213x^3and the last two terms without partners

Best ResponseYou've already chosen the best response.0yes :) well done, by the way.. there is a difference between (5x)^2 and 5x^2.. do you know it?

Best ResponseYou've already chosen the best response.0(5x)^2= 5^2x^2=25x^2 5x^2 is just 5x^2 :) next time you should write your question with the exponents to avoid complications :)
