Question

x cube-8y cube
fast answer​

Answer 1

Answer:

Step-by-step explanation:

x^3 - 8y^3

= x^3 - (2y)^3

formula - (a^3 – b^3) = (a – b)(a^2 + b^2 + ab)

here a = x and b = 2y

therefore,

(x^3 – (2y)^3) = (x – 2y ) (x^2 + (2y)^2 + 2xy)

                      = (x – 2y ) (x^2 + 4y^2 + 2xy)

Answer 2

(x-2y) (x^2+2xy+4y^2)
