Add polynomials (intro) Add. Your answer should be an expanded polynomial in standard form. (-4b^2 +8b) + (-4b^3 + 5b^2 - 8b)

Step-by-step explanation:

Hey there!

Given;

Open brackets.

Simplify the like terms.

"+8b" and "-8b" cancelled. And "-4b^2" and "+5b^2" will be subtracted.

Therefore the required answer is -4b^3+b^2.
