Question

Factorize the following. x4 - 8x2y2 + 16 y4 - 256​

Answer 1

Step-by-step explanation:

$x^{4}+16y^{4}-8x_{2}y^{2}-256$

$\left(x^{2}-4y^{2}-16\right)\left(x^{2}-4y^{2}+16\right)$

$\left(x^{2}-4y^{2}\right)^{2}-256$

Answer 2

Answer:

(x² - y² + 4²) (x² - y² - 4²)

Step-by-step explanation:

(x²)² 2* x² * 4y² + (4y²)² - 16²

(x²- y²) ² - (4²)²

= (x²- y² + 4²) (x² - y² -4²)
