Simplify (6x2 - 3 + 5x3) - (4x3 - 2x2 - 16).

2x3 - x2 + 21

-2x3 + x2 - 21

x3 + 8x2 + 13

-x3 - 8x2 + 13

If you would like to simplify (6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16), you can calculate this using the following steps:

(6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16) = 6x^2 - 3 + 5x^3 - 4x^3 + 2x^2 + 16 = x^3 + 8x^2 + 13

The correct result would be x^3 + 8x^2 + 13.
