There is something im not getting with this limit and its like a roadblock for the rest of the Homework because i been getting similar results on the next few problems.

lim (X-1) / [sr(x+3)-2]

x-1

answer is 4

I assume i must use the conjugate method and mult the top and bottom by (srx+3)+2 but doing that with the dem i get [x-3]-4 on the bottom which cant work because the dem. can't be zero!

since i thought it might be a trick question i tied taking the conj of the top but i end up with the anwser 1/4 which is wrong too.

so how do i do this? thanks

edit really sorry i forgo tthe SR at the end of hte problem
