Question

x-2y-x²+4y² factorise​

Answer 1

Answer:

x - 2y - x² + 4y²

= (x - 2y) - (x² - 4y²)

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

= (x - 2y) (1 - x - 2y),

which is the required factorization.

Answer 2

Answer:

Now,

x - 2y - x² + 4y²

= (x - 2y) - (x² - 4y²)

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

= (x - 2y) (1 - x - 2y)
