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

By using horizontal method,We have;= (x2 – y2) × (x + 2y)= x2 (x + 2y) – y2(x + 2y)= x3 + 2x2y – xy2 – 2y3

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

By using horizontal method,

We have;

= (x² – y²) × (x + 2y)

= x² (x + 2y) – y²(x + 2y)

= x³ + 2x²y – xy² – 2y³

(3m – 4n) × (2m – 3n)

Find each of the following products:

(x² – a²) × (x – a)

Find each of the following products:

(3p² + q²) × (2p² – 3q²)

Find each of the following products:
