Question

Find the difference of (−5x2 − x3 − 3) − (9x3 + 3x − 6x2). Be sure to show all of your work in a neat and organized fashion.

Answer 1

So what I would do first is take the parentheses out. -5x^2 - x^3 -3 - 9x^3 - 3x + 6x^2. Then you would combine your like terms. -10x^3 + x^2 - 3x - 3 should be the final answer.

Answer 2

Just distribute the negative and combine all the like terms :)

Answer 3

thank you!
