factorise the numerator and the denominator first

OpenStudy (anonymous):

done (x+1)^2/(x-2)(x-6)

OpenStudy (unklerhaukus):

well nothing cancels this time , but thats ok. now, look at the denominator y there are two values of x that would make the denominator equal to zero , when the denominator of a function equals zero, this is an asymptote of the function , do you know what i mean by that?

OpenStudy (anonymous):

denomiantor is (x-2) (x-6)=0

OpenStudy (anonymous):

x=2 and 6

OpenStudy (unklerhaukus):

thats right, these are where the asymptotes are, do you know what that means ?

OpenStudy (unklerhaukus):

The function is not defined at a asymptote
