Question

expand
(a+b)^3
show me the formula

Answer 1

(a + b)³ = a³ + b³ + 3ab(a + b)
(a - b)³ = a³ + b³ - 3ab(a - b)

Answer 2

Heya,

(a+b)³ =a³+ b³+ 3a²b+ 3ab² by algebraic identities

Here this can used as the expanded form of (a+b)³

This can also be written  as a³+b³ + 3ab(a+b)

Hope it helps u...............
