Simplify the difference. (-7x - 5x4 5) - (-7x4 - 5 - 9x) a. 2x4 2x 10 b. - 14x4 10x 10 c. - 14x4 - 10x 10 d. 2x4 2x 8

If you would like to simplify the difference (-7x - 5x^4 + 5) - (-7x^4 - 5 - 9x), you can do this using the following steps:

(-7x - 5x^4 + 5) - (-7x^4 - 5 - 9x) = - 7x - 5x^4 + 5 + 7x^4 + 5 + 9x = 2x^4 + 2x + 10

The correct result would be a. 2x^4 + 2x + 10.
