Answer:

$3a {b}^(2) + {a}^(2) - {b}^(2) - ab$

Explanation:

${ - 2a}^(2)b + {a}^(2) - 5ab + 3a {b}^(2) - {b}^(2) + 2( {a}^(2) + 2ab)$

$- 2 {a}^(2) b +{a}^(2) - 5ab + 3a {b}^(2) - {b}^(2) + 2 {a}^(2) b + 4ab$

$0 {a}^(2) b + {a}^(2) - ab + 3a {b}^(2) - {b}^(2)$

$3a {b}^(2) + {a}^(2) - {b}^(2) - ab$
