Answer 1

ANSWER:

Factorisation of x^3+1

(x+1)(x^2-x+1)

Answer 2

Answer:

x= -1, -w (minus omega) , -w^2(minus omega square)

Step-by-step explanation:

$w = (- 1 + \sqrt{3} i) \div 2$

$- w = (1 - \sqrt{ - 3} ) \div 2$

$w {}^{2} =( - 1 - \sqrt{3} i) \div 2$

$- w {}^{2} = (1 + \sqrt{ - 3} ) \div 2$
