Question

Choose the correct sum of the polynomials (6x^3 − 8x − 5) + (3x^3 + 6x + 2).

9x^3 − 2x − 3
3x^3 + 2x + 3
3x^3 − 2x − 3
9x^3 + 14x + 3

Answer 1

option 1 thank you next

Explanation:

Answer 2

For this case we have the following polynomials:

`6x ^ 3 - 8x - 5 3x ^ 3 + 6x + 2`
Adding the polynomials we have:

`(6x ^ 3 - 8x - 5) + (3x ^ 3 + 6x + 2)`
To add the polynomials, we must add terms of the same exponent.
We have then:

`x ^ 3 (6 + 3) + x (-8 + 6) + (-5 + 2)`
Rewriting we have:

`9x ^ 3 - 2x - 3`
Answer:
The correct sum of the polynomials is:

`9x ^ 3 - 2x - 3`
