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

1.	Find each of the following products: (x4 + y4) × (x2 – y2)
Answer» By using horizontal method, We have; = (x⁴ + y⁴) × (x² – y²) = x⁴(x² – y²) + y⁴(x² – y²) = x⁶ – x⁴y² + x²y⁴ – y⁶

Answer»

By using horizontal method,

We have;

= (x⁴ + y⁴) × (x² – y²)

= x⁴(x² – y²) + y⁴(x² – y²)

= x⁶ – x⁴y² + x²y⁴ – y⁶
