Answer 1

To add the polynomial expressions, combine like terms:

Expression #1: 3x^4 - 2x^3 + 4x - 2

Expression #2: 2x^3 - 6x - 4

Adding them together, we get:

(3x^4 - 2x^3 + 4x - 2) + (2x^3 - 6x - 4)

Simplifying, we get:

3x^4 - 2x^3 + 4x - 2 + 2x^3 - 6x - 4

Combining like terms, we get the final result:

3x^4 + 2x^3 - 2x - 8
