Answer:

6x^5-5x^4+6x^3-x^2+12x+-31

Step-by-step explanation:

The question is to simplify (add) the expression shown below:

(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)

<em>We can get rid of the parenthesis and add like terms:</em>

(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)\\=-5x^4+6x^3-43+6x^5-x^2+12x+12\\=6x^5-5x^4+6x^3-x^2+12x+12-43\\=6x^5-5x^4+6x^3-x^2+12x+-31


<em>standard form means to keep the terms in descending order of powers, which is already shown.</em>
