Factorize each of the following algebraic expressions:4x4 + y4

1.	Factorize each of the following algebraic expressions:4x4 + y4
Answer» (2x²)² + (y²)² + 4x²y² – 4x²y² = (2x²+ y²)² – 4x²y² = (2x² + y² + 2xy) (2x² + y² – 2xy)

Answer»

(2x²)² + (y²)² + 4x²y² – 4x²y²

= (2x²+ y²)² – 4x²y²

= (2x² + y² + 2xy) (2x² + y² – 2xy)
