Find all the numbers for which the rational expression is undefined
s^3-6x/ s^2-9
Thanks for the help
Answered by Reiny
an undefined situation arises if one attempts to divide by zero.

So I toss the question back to you,
for what values of s is (s^2 - 9) equal to zero ?
(hint: there are two of them)
Answered by jennie
The two values are s=3,-3 is this the right values?
