Question 604852: find all numbers for which the rational expression is undefined m^3-8m/m^2-49
Answer by nerdybill(7384) (Show Source): You can put this solution on YOUR website!
It would be undefined if the denominator is zero, so:
m^2-49 = 0
m^2 = 49
m = +- 7
.
So, it is undefined if
m = -7
or
m = 7
