Plug in the value of x (-5) and simplify as follows :
[tex]\displaystyle\frac{5(-5)+25}{2(-5)^2-50}[/tex]
[tex]\displaystyle\frac{-25+25}{2(25)-50}[/tex]
[tex]\displaystyle\frac{0}{50-50}[/tex]
[tex]\displaystyle\frac{0}{0}[/tex]
We know that we can't divide by zero. Dividing by zero results in infinity , which is not a number .
So the expression is :
