Question

1. (m^2 - m - 4) + (m - 5)
m^2 - 2m + 9
m^2 + 2m - 9
m^2 - 2m - 9
m^2 - 9

2. (4x^2 - 2x - 1) - (-3x^3 + 2)
-3x^3 + 4x^2 - 2x + 1
-3x^3 + 4x^2 - 2x - 3
3x^3 + 4x^2 - 2x + 1
3x^3 + 4x^2 - 2x - 3

Answer 1

First is D.

Answer 2

That's the one I picked but wasn't sure.

Answer 3

Good, what did you pick as the second one?

Answer 4

On the second one I got -3 + 4x^2 - 2x + 3x^3

Answer 5

That one was actually 3x^3 + 4x^2 - 2x - 3.

Answer 6

So it would be D again?

Answer 7

Yep.

Answer 8

Thanks! :)

Answer 9

No problem.
