Find all numbers for which the rational expression is undefined. (s^(3)-7s)/(s^(2)-16)

# Find All Numbers For Which The Rational Expression Is Not Defined: (x^2-49)/(x^2 +4x-12),can You Help Me ?

X = -6 or x = +2 are the roots of the denominator. At those points, the expression is indeterminate or undefined. You answer such questions by finding the roots of the denominator quadratic.
