Answer 1

Answer:

Done

Step-by-step explanation:

Use the identity

a³ + b³ + c³ - 3abc = (a + b + c)(1/2)((a - b)² + (b - c)² + (c - a)²)

This form will be useful when you will study maths in class 12th

If you are junior, one more form of the given expression is there,

a³ + b³ + c³ - 3abc = (a + b + c)(a² + b² + c² - ab - bc - ca)

So, if you put a = 3x, b = y, and c = z

You will get the required factorisation
