Question

Find the difference of (−4x^2 − 7x^3 − 2) − (8x^3 + 3x − 7x2). 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.

Answer 1

Okay first this is what you do : (−4x^2 − 7x^3 − 2) − (8x^3 + 3x − 7x^2)
remove the parentheses (signs will change in the second one)
-4x^2 - 7x^3 - 2 - 8x^3 - 3x + 7x^2
then you would have to
combine like terms (x^3 with x^3; x^2 with x^2 etc) which would be.
- 15x^3 + 3x^2 - 3x - 2
