Factorize:1 – 27 x3

We know that,a3 - b3 = (a - b) (a2 + a × b + b2)Using this formula, we get= (1)3 – (3x)3= (1 – 3x) [(1)2 + 1 (3x) + (3x)2)= (1 – 3x) (1 + 3x + 9x2)

1 – 27 x³

We know that,

a³ - b³ = (a - b) (a² + a × b + b²)

Using this formula, we get

= (1)³ – (3x)³

= (1 – 3x) [(1)² + 1 (3x) + (3x)²)

= (1 – 3x) (1 + 3x + 9x²)
