Question

How do you simplify `(x^2-25)/(x^2+5x)` and what are the ecluded values fot he variables?

Answer 1

`(x^2-25)/(x^2+5x)=color(green)(1-5/x, xcancel(in){-5,0})`

Explanation:

`(x^2-25)/(x^2+5x)=((x-5)(cancel(x+5)))/(x(cancel(x+5)))` provided `x!=-5`

`color(white)("XXX")=1-5/x` provided `x!=0`
