Question

Factorisation of x3+ 1 is​

Answer 1

Answer:

(x+1)(x²-x+1)

Step-by-step explanation:

x³+1

=x³+1³

=(x+1)(x²-x+1) ...........{a³+b³=(a+b)(a²-ab+b²)}

Answer 2

Answer:

(x + 1)(x² - x + 1)

Step-by-step explanation:

x³ + 1

(x)³ + (1)³

Using identity a³ + b³ = (a + b)(a² - ab + b²)

(x + 1)(x² - x.1 + 1²)

(x + 1)(x² - x + 1)
