Answer:

A.
12x^(4) -4x^(3) +3x^(2) +3x+20

Explanation:

For this problem, we have to combine like terms.

Let's look at the equation:


(12x^(4) -4x^(3) +7x+6)+(3x^(2) -4x+14)


12x^{4,
-4x^(3),
3x^(2) do not have any other like terms, so we keep all in the final answer.


7x and
-4x are like terms, so we combine them.
7x-4x=3x

14 and 6 are like terms, so we combine them. 14+6 = 20

Let's put everything into the final equation:


12x^(4) -4x^(3) +3x^(2) +3x+20

So, the final answer is A.
12x^(4) -4x^(3) +3x^(2) +3x+20

Hope this helps! If you have any questions about my work, leave them in the comments below!
