Question

Q14. x² + y - x - xy ..​

Answer 1

Answer:

x=y

Step-by-step explanation:

x/(x-y)  -   y/(x+y)   - 2xy/(x²-y²)

= x(x+y)-y(x-y)/(x²-y²)    - 2xy/(x²-y²)

=(x²+xy-xy+y²-2xy)/(x²-y²)

=(x²+y²-2xy)/(x²-y²)

=(x-y)²/(x-y)(x+y)

=(x-y)/(x+y)

Answer 2

Step-by-step explanation:

x^2 + y - x - xy

x^2 - x + y - xy

(x^2 - x) (y - xy)

x( x - 1) -y( -1 + x)

x( x - 1) -y(x - 1)

(x - 1)(x - y)
