Question

(x+y)²-(x-y)²/x²y-xy²​

Answer 1

Step-by-step explanation:

(x+y)^2= x^2+y^2+2xy

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

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

multiply the minus inside,

(x^2+y^2+2xy-x^2-y^2+2xy)/x²y-xy²

4xy/x²y-xy²

x²y-xy² can be rewritten as,

xy(x-y)

therefore,

4xy/xy(x-y)

xy gets cancelled,

therefore the answer is 4/x-y
