Question 322515: Find all numbers for which rational expression is undefined,
t^3-3t/t^2-49
My original answer was t(t^2-3)/(t-7)(t+7)
Mr Thompson gave me a hint on how to do this properly because that was not the correct answer.
My new answer -7,7
Is this correct?

You are correct. The values -7 and 7 make the rational expression undefined because, when plugged in, they cause a division by zero error.
