Question

Factorise
a cube +b cube +c cube -3abc

Answer 1

Answer:

(a+b+c)($a^{2}$ + $b^{2} + c^{2} - ab - bc - ca)$

Step-by-step explanation:

Let's use the formula :

(a+b+c)($a^{2}$ + $b^{2} + c^{2} - ab - bc - ca)$=$a^{3} + b^{3} + c^{3} - 3abc$

So the answer is : (a+b+c)($a^{2}$ + $b^{2} + c^{2} - ab - bc - ca)$
