Resolve into factor: {Σ_(x, y,z) x}³ - Σ_(x, y,z) x³.

Step-by-step explanation:

Given expression is

can be rewritten as

can be further rewritten as

We know,

and

So, using these Identities, we get

Hence,

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(a + b)² = a² + 2ab + b²

(a - b)² = a² - 2ab + b²

a² - b² = (a + b)(a - b)

(a + b)² = (a - b)² + 4ab

(a - b)² = (a + b)² - 4ab

(a + b)² + (a - b)² = 2(a² + b²)

(a + b)³ = a³ + b³ + 3ab(a + b)

(a - b)³ = a³ - b³ - 3ab(a - b)

found it xd it ok yt
