Find each of the following products: (x2 – y2) × (x + 2y)

1.	Find each of the following products: (x2 – y2) × (x + 2y)
Answer» By using horizontal method, We have; = (x² – y²) × (x + 2y) = x² (x + 2y) – y²(x + 2y) = x³ + 2x²y – xy² – 2y³

Answer»

By using horizontal method,

We have;

= (x² – y²) × (x + 2y)

= x² (x + 2y) – y²(x + 2y)

= x³ + 2x²y – xy² – 2y³
