Question 450742: Find all numbers for which the rational expression is undefined:
m^3 - 4m
--------
m^2 - 81
I do not have any work on this, but I know that the first step is to make the denominator = to 0.
then to solve for m. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Find all numbers for which the rational expression is undefined:
m^3 - 4m
--------
m^2 - 81
:
Yes, just do that
m^2 - 81 = 0
m^2 = 81
m = +/-
m = 9
and
m = -9
:
undefined when m = 9 and m = -9
