Answer:
see below
Step-by-step explanation:
[tex]y-\frac{4x^5}{x^{2}-xy }[/tex] find common denominator and rewrite 1st part as a fraction
[tex]\frac{y(x^{2}-xy) }{x^{2}-xy }[/tex] [tex]-\frac{4x^5}{x^{2} -xy}[/tex]
[tex]\frac{x^{2}y - xy^2 -4x^5 }{x^{2} -xy}[/tex]
[tex]\frac{x(xy-y^2-4x^4}{x(x-y)}[/tex]
[tex]\frac{xy-y^{2}-4x^4 }{x-y}[/tex]
