Question

Add the following polynomials then place the answer in the proper location 2x^3+4x-6 3x^3-8x+7​

Answer 1

5x^3 - 4x + 1

Explanation:

To add the polynomials, combine like terms which ha the same variable and exponent.

`2x^3 + 4x - 6 + 3x^3 - 8x + 7`

2x^3 + 3x^3 = 5x^3

4x - 8x = -4x

-6 + 7 = 1

So it adds to 5x^3 - 4x + 1
