Mathematics

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

Step-by-step explanation:

The expression for sum of cube is given as:

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

When we put a=2x and b=y into this formula, we obtain:

(2x)^3+y^3=(2x+y)[(2x)^2-2x*y+y^2]

We simplify to get:

8x^3+y^3=(2x+y)[4x^2-2xy+y^2]

Therefore the correct choice is (2x+y)(4x^2-2xy+y^2)
