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:

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

We can get rid of the parenthesis and add like terms:

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

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