Find each of the following products:(2x2 – 5y2) × (x2 + 3y2)

By using horizontal method,We have;= (2x2 – 5y2) × (x2 + 3y2)= 2x2(x2 + 3y2) – 5y2(x2 + 3y2)= 2x4 + 6x2y2 – 5x2y2 – 15y4= 2x4 + x2y2 – 15y4

Find each of the following products:
(2x² – 5y²) × (x² + 3y²)

By using horizontal method,

We have;

= (2x² – 5y²) × (x² + 3y²)

= 2x²(x² + 3y²) – 5y²(x² + 3y²)

= 2x⁴ + 6x²y² – 5x²y² – 15y⁴

= 2x⁴ + x²y² – 15y⁴

Find each of the following products:

(x² – y²) × (x + 2y)

Find each of the following products:

(3p² + q²) × (2p² – 3q²)

Find each of the following products:

(x³ – y³) × (x² + y²)

Find each of the following products:

(x⁴ + y⁴) × (x² – y²)
