For this case we have the following polynomials:
[tex]6x ^ 3 - 8x - 5
3x ^ 3 + 6x + 2[/tex]
Adding the polynomials we have:
[tex](6x ^ 3 - 8x - 5) + (3x ^ 3 + 6x + 2)
[/tex]
To add the polynomials, we must add terms of the same exponent.
We have then:
[tex]x ^ 3 (6 + 3) + x (-8 + 6) + (-5 + 2)
[/tex]
Rewriting we have:
[tex]9x ^ 3 - 2x - 3
[/tex]
Answer:
The correct sum of the polynomials is:
[tex]9x ^ 3 - 2x - 3
[/tex]
