Question

The factore of (1-x^3)are​

Answer 1

Answer:

(1 - x)³ + 3x( 1 + x)

Step-by-step explanation:

(a - b)³ = a³ - b³ - 3ab(a + b)

=> a³ - b³ = (a - b)³ + 3ab(a + b)

Therefore, (1 - x³) which is also equal to (1³ - x³), we expand this to (1 - x)³ + 3 × 1 × x(1 + x)

= (1 - x)³ + 3x( 1 + x)
