Step-by-step explanation:

I took the test and put what the other person said and got it wrong and saw that that was the right answer

Answer 2

To add expressions, you should take note that you can only combine same terms which means they have the same degree of exponents.

-5x^4 + 6x^3 – 43 + 6x^5 – x^2 + 12x + 12

In this expression, you can only combine the constants because they are the only similar terms:

-5x^4 + 6x^3 + 6x^5 – x^2 + 12x + 12 – 43

-5x^4 + 6x^3 + 6x^5 – x^2 + 12x – 31

The standard form starts with the term with the highest exponent so you just have to arrange the terms:

6x^5 - 5x^4 + 6x^3 – x^2 + 12x + 12
