Question

FACTORISE THE FOLLOWING :-

x - 2y – x² + 4y²​

Answer 1

Step-by-step explanation:

Step-by-step explanation:(x-x²)(-2y+4y²)

Step-by-step explanation:(x-x²)(-2y+4y²)x(2y+4y²)-x²(-2y+4y²)

Step-by-step explanation:(x-x²)(-2y+4y²)x(2y+4y²)-x²(-2y+4y²)(2xy+4xy²)+(2x²y+4y²)

Step-by-step explanation:(x-x²)(-2y+4y²)x(2y+4y²)-x²(-2y+4y²)(2xy+4xy²)+(2x²y+4y²)2xy+4xy²+2x²y+4y²

Step-by-step explanation:(x-x²)(-2y+4y²)x(2y+4y²)-x²(-2y+4y²)(2xy+4xy²)+(2x²y+4y²)2xy+4xy²+2x²y+4y²(2xy+2x²y)+(4xy²+4y²)

Step-by-step explanation:(x-x²)(-2y+4y²)x(2y+4y²)-x²(-2y+4y²)(2xy+4xy²)+(2x²y+4y²)2xy+4xy²+2x²y+4y²(2xy+2x²y)+(4xy²+4y²)2x(y+xy)+4y²(x+1)

Answer 2

Answer:

x-2y-x²+4y²

=(x-2y) -(x²-4y²)

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

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