Question

factorise x² – 3x + 3y - y²​

Answer 1

Answer:

(x - y)(x + y - 3)

Step-by-step explanation:

given :- x² - 3x + 3y - y²

=> x² - y² - 3x + 3y

=> (x + y)(x - y) - 3(x - y)

=> (x - y)[(x + y - 3)]

=> (x - y)(x + y - 3)

Answer 2

x² – y² – 3x – 3y

= (x² - y² ) – 3 (x + y)

= (x + y) (x – y) – 3(x + y)

= (x + y) (x – y – 3)
