Question 422883: Find all the numbers which make the rational expression undefined:
p^3-6p/p^2-4

This one is MUCH easier than it looks!! You have to ask yourself, "What makes a fraction UNDEFINED?" The answer is "DENOMINATOR = ZERO."
So, make the denominator equal to zero (which we ALL know is NEVER really allowed in math!!), and solve the equation.
x= 2 or x= -2
