We know that, a 3 + b 3 = (a + b) (a 2 – a × b + b 2 ) Using this formula, we get = (1) 3 + (4x) 3 = (1 + 4x) [(1) 2 – 1 (4x) + (4x) 2 ] = (1 + 4x) (1 – 4x + 16x 2 )

We know that,

a³ + b³ = (a + b) (a² – a × b + b²)

Using this formula, we get

= (1)³ + (4x)³

= (1 + 4x) [(1)² – 1 (4x) + (4x)²]

= (1 + 4x) (1 – 4x + 16x²)
