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.

yes your answer is right but your method is fishy.. any go on :) i would say 5x^28x^2 = 5x^2+8x^2=3x^2

bronzegoddessBest ResponseYou've already chosen the best response.2
well, the 9 is postive but you have to subtract it from 4..

4x^39x^3 is the same as 4x^3+9x^3

bronzegoddessBest ResponseYou've already chosen the best response.2
yes, and the last two terms, do they have partners?
 one year ago

bronzegoddessBest ResponseYou've already chosen the best response.2
lol, 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

so 3x^2  13^3 + 3x  3?
 one year ago

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

bronzegoddessBest ResponseYou've already chosen the best response.2
(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 :)
