Question

Change the following mixed expressions to fractions and then simplify the complex fractions.

y-(4x^(5))/(x^(2)-xy)

Answer 1

Answer:

see below

Step-by-step explanation:

$y-\frac{4x^5}{x^{2}-xy }$ find common denominator and rewrite 1st  part as a fraction

$\frac{y(x^{2}-xy) }{x^{2}-xy }$ $-\frac{4x^5}{x^{2} -xy}$

$\frac{x^{2}y - xy^2 -4x^5 }{x^{2} -xy}$

$\frac{x(xy-y^2-4x^4}{x(x-y)}$

$\frac{xy-y^{2}-4x^4 }{x-y}$
