Question

Factorise x^2-y^2+4y+4​

Answer 1

Answer: x^2 - y^2 + 4y + 4

i think its correct hopefully it helps. goodluck! :))

Answer 2

Answer:

x² - y² + 4y + 4

= (x)² - [(y)² + 2 (y × 2) + 2²]

= (x)² - (y - 2)²

= (x + y + 2)(x - y + 2) .

This is the factorised form of x² - y² + 4y + 4 .

Hope it helps you !
