Find each of the following products:(x4 + y4) × (x2 – y2)

By using horizontal method,We have;= (x4 + y4) × (x2 – y2)= x4(x2 – y2) + y4(x2 – y2)= x6 – x4y2 + x2y4 – y6

Find each of the following products:
(x⁴ + y⁴) × (x² – y²)

By using horizontal method,

We have;

= (x⁴ + y⁴) × (x² – y²)

= x⁴(x² – y²) + y⁴(x² – y²)

= x⁶ – x⁴y² + x²y⁴ – y⁶

Find each of the following products:

(2x² – 5y²) × (x² + 3y²)

Find each of the following products:

(x³ – y³) × (x² + y²)

Find each of the following products:

(x² – 3x + 7) × (2x + 3)
