the answer is 5b^4-7b^3-6b^2

Explanation:

first you have to distribute 5b^2 to everything on the other sides so:5b^2*b^2 and 5b^2*-2b and now do the same for 3b so you'll have3b*b^2 and 3b*-2b and all together:5b^4-10b^3+3b^3-6b^2 and now combine like terms. combine terms with the same exponents and you get your answer

6b^2 +b

Explanation:

So this is actually a really simple question.

First off you got to distribute the plus sign.

(5b^2 + 3b) +b^2 - 2b

Now you just add like terms.

5b^2+b^2 +3b - 2b

So your finally answer will be:

6b^2 +b
