Question

What is the simplified expression for –2a2b + a2 – 5ab + 3ab2 – b2 + 2(a2b + 2ab)?

Answer 1

this is as simplified as it can get answer 5 a b + 2 a - 2 b

Answer 2

`a^2- ab + 3ab^2 - b^2`

Explanation:

`-2a^2b + a^2- 5ab + 3ab^2 - b^2 + 2(a^2b + 2ab)`

To simplify the expression we need to remove the parenthesis

`-2a^2b + a^2- 5ab + 3ab^2 - b^2 + 2a^2b + 4ab`

Now combibne like terms

`-2a^2b+2a^2b=0`

`- 5ab + 4ab=-ab`

`-2a^2b + a^2- 5ab + 3ab^2 - b^2 + 2a^2b + 4ab`

`a^2- ab + 3ab^2 - b^2`
