Question

How do you combine `(5b^2 + 3b) + (b^2 - 2b)`?

Answer 1

`6b^2+b`

Explanation:

`(5b^2+3b)+(b^2-2b)`
=`5b^2+3b+b^2-2b`
= `6b^2+b`

Answer 2

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 have`3b*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

Answer 3

`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`
