The expression will be simplified as [tex]\dfrac{x^2+2x-xy}{y^2-x^2}[/tex].
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression will be simplified as follows:-
[tex]\dfrac{2x}{y^2-x^2}-\dfrac{x}{y-x} = \dfrac{2x-x(y-x)}{y^2-x^2}\\\\[/tex]
[tex]=\dfrac{2x-xy+x^2}{y^2-x^2}[/tex]
[tex]= \dfrac{x^2+2x-xy}{y^2-x^2}[/tex]
Therefore the expression will be simplified as [tex]\dfrac{x^2+2x-xy}{y^2-x^2}[/tex].
