Choose the correct sum of the polynomials (3x3 - 5x - 8) + (5x3 + 7x + 3).

8x3 + 2x + 5

2x3 - 12x - 11

2x3 + 12x - 5

8x3 + 2x - 5

If you would like to solve (3x^3 - 5x - 8) + (5x^3 + 7x + 3), you can do this using the following steps:

(3x^3 - 5x - 8) + (5x^3 + 7x + 3) = 3x^3 - 5x - 8 + 5x^3 + 7x + 3 = 8x^3 + 2x - 5

The correct result would be 8x^3 + 2x - 5.
