Question

subtract (2ab^2+3a^2b- 4ab ) - ( 3ab -8ab^2 + 2a^2b) ​

Answer 1

Answer:

$(2ab^{2} + 3 {a}^{2} b - 4ab) - (3ab - 8a {b}^{2} + 2 {a}^{2} b) \\ = 2ab^{2} + 3 {a}^{2} b - 4ab \: - 3ab + 8a {b}^{2} - 2 {a}^{2} b \\ writing \: like \: terms \: together\\ = 3 {a}^{2} b - 2 {a}^{2} b + 2ab ^{2}+ 8a {b}^{2} \: - 4ab \: - 3ab \\ = {a}^{2} b + 10a {b}^{2} - 7ab$
