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

Answer:

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

Step-by-step 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

$-2a^2b+2a^2b=0$  

$- 5ab + 4ab=-ab$

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

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