Points of discountity

how do we find the points of discountity of
f(x)=8x/5x^2-1?
 
If i made the denominator =0 i would get squared 1/5 and then when i will plug it back it will be undefined or am i doing it wrong !

Indeed, it's not 'legal' to plug a zero of the denominator into the rational algebraic function!  DOMAIN violation!
