(7x-6y) (49x^2+42xy+36y^2)

Step-by-step explanation:

Given, 343x^3-216y^3

We can also write this as (7x)^3+(6y)^3

We use the formula a^3-b^3=(a-b) (a^2+ab+b^2)

In the above question a=7x and b=6y

Applying formula, we get

(7x)^3+(6y)^3 = (7x-6y) (7x^2+(7x)(6y)+6y^2)

Simplifying,

(7x)^3+(6y)^3 = (7x-6y) (49x^2+42xy+36y^2)
