Answer:

The excluded value is x=5.

Step-by-step explanation:

Given : Expression  \frac{2x}{-5x+x^2}

To find : Simplify the rational expression. State any excluded values.      

Solution :

First we simplify the expression,

\frac{2x}{-5x+x^2}

Taking x common from the denominator,

=\frac{2x}{x(-5+x)}

Cancel the common term from numerator and denominator,

=\frac{2}{-5+x}

To find the excluded value we put the denominator equal to zero to get the value of x in which given expression is not valid.

-5+x=0

x=5

Therefore, The excluded value is x=5.
