Answer 1

The fraction will be undefined on x=5 and x=-5

Given fraction is:

$\frac{5x-10}{x^2-25}$

To find the values on which the denominator will be zero, we put the denominator equal to zero.

$x^2-25=0\\(x)^2-(5)^2=0\\(x+5)(x-5)=0\\x+5 = 0 => x=-5\\x-5 = 0 => x=5$

So,

The fraction will be undefined on x=5 and x=-5
