Add: (2x^5−6x^3−12x^2−4)+(−11x^5+8x+2x^2 +6).

Step-by-step explanation:

(2x^5−6x^3−12x^2−4)+(−11x^5+8x+2x^2+6).

since its addition we can remove the parenthesis and simply list them

so

Personally I order them before adding, it makes it easier for me.

so

now its easier if you group them in order of having the same exponent

so

now solve whats in parenthesis. you will see when you're finished that its already ordered too.
