Question

a plus b ka whole cube ka formula batado

Answer 1

$a ^{3} + b ^{3} + 3a ^{2} b + 3 ab ^{2}$

Answer 2

Hey guys here is your answer!!

==========================

Formula of (a + b)³


(a + b)³


［(a + b)(a + b)］(a + b)

［a(a + b) + b(a + b)］（a + b)

(a² + ab + ab + b²) (a + b)

a ( a² + 2ab + b²) + b(a² + 2ab + b²)

a³ + 2a²b + ab² + a²b + 2ab² + b³

a³ + 3a²b + 3ab² + b³

a³ + b³ + 3a²b + 3ab²

a³ + b³ + 3ab( a + b)


Therefore ......

(a + b)³ = a³ + b³ + 3ab(a + b)
