Answer: 3x^4 +x^3 -2x^2 +3x +2

Step-by-step explanation:

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

There are no like terms for 3x^4, so leave it alone.

-2x^3 + 3x^3 = 1x^3

No like terms for -2x^2

4x - x = 3x

-2 + 4 = 2

Answer? 3x^4 +x^3 -2x^2 +3x +2

Answer:

B. 3x4 + x3 - 2x2 + 3x + 2

Step-by-step explanation:

3x4 - 2x3 + 4x - 2 + 3x3 - 2x2 - x + 4 add the like terms (the ones with same power)

3x4 (there's no other term with 4th power so we leave this one as it is)

-2x3 + 3x3 = x3

-2x2 (this one as well will be as it is)

4x - x = 3x

-2 + 4 = 2
