Question 973322: Find the removable discontinuity of the rational function:
f(x)=x^2+x-2/x^2-x-6

You can put this solution on YOUR website! I will tell you what to do, and then you do it and decide.
Factorize the numerator and factorize the denominator. If you find an occurance of the same factor in both numerator and denominator, then each pair like that will force a removable discontinuity.
A factor occuring once in BOTH the numerator and the denominator makes a removable discontinuity for when x-c=0, if the binomial factor is x-c.
