Answer 2

Answer:

[x² + (y - 1)²] [(x - y + 1)(x + y - 1)]

Step-by-step explanation:

Given : x⁴ - (y - 1)⁴

We can write this as :

→ (x²)² - [(y - 1)²]²

Identity : a² - b² = (a + b)(a - b)

Here, a = x², b = (y - 1)²

→ [x² + (y - 1)²] [x² - (y - 1)²]

We can write this as :

→ [x² + (y - 1)²] [(x)² - (y - 1)²]

Identity : a² - b² = (a - b)(a + b)

Here, a = x, b = y - 1

→ [x² + (y - 1)²] {[x - (y - 1)] [x + (y - 1)]}

→ [x² + (y - 1)²] [(x - y + 1)(x + y - 1)]
