(2x + y) ³

(2x + y) (2x + y) (2x + y)

(2x (2x + y) + y (2x + y)) (2x + y)

(2x (2x) + 2x (y) + y (2x) + y (y)) (2x + y)

(4x² + 2xy + 2xy + y²) (2x + y)

(4x² + 4xy + y²) (2x + y)

4x² (2x + y) + 4xy (2x + y) + y² (2x + y)

4x² (2x) + 4x² (y) + 4xy (2x) + 4xy (y) + y² (2x) + y² (y)

8x³ + 4x²y + 8x²y + 4xy² + 2xy² + y³

8x³ + 12x²y + 6xy² + y³
