Question

Find the difference of (-5x^2 - 4x^3 - 3) - (9x^3 + 3x - 8x^2). 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. Find the difference of (-5x^2 - 4x^3 - 3) - (9x^3 + 3x - 8x^2). Be sure to show all of your work in a neat and organized fashion.

Answer 1

−5x^2 − 4x^3 − 3) − (9x^3 + 3x − 8x^2)
= −5x^2 − 4x^3 − 3 − 9x^3 − 3x + 8x^2
Combine like terms:
= (−4 − 9)x^3 + (−5 + 8)x^2 − 3x − 3
= −13x^3 + 3x^2 − 3x − 3
