Answer 1

Are bhai kya Karna hai

agar subtract Karna hai to

Answer:

a^3-3a^2b+3ab^2-(b^3-4ab^2-4a^2b

=> a^3-b^3-3a^2b+4a^2b+3ab^2+4a^2b

=> a^3-b^3+a^2b+7ab^2 ans

I hope it is useful for you

Answer 2

Answer:

(a-b) (6ab-a²-b²)

Step-by-step explanation:

b³-4ab²-4a²b-a³-3a²b+3ab²

= -a³-3a²b+3ab²+b³-4a²b-4ab²

= -(a-b)³ + 4ab(a-b)

= (a-b) {4ab- (a²+b²-2ab)}

= (a-b) {6ab-a²-b²}
