oh I know I cancel out the y's
I will have 4x^2/3
Determine the Values for Which a Rational Expression is Undefined
In the following exercises, determine the values for which the rational expression is undefined
4x^2y/3y....y=0
Whats the best way for me to grasp this concept.
I have reread the examples from my book but Im not understand what they are doing exactly.

that's right.
4x^2y/3y = 4x^2/3
for all values of x and y except y=0
When y=0, you have 0/0 which is undefined.
