Please help, can't seem to factor the top portion at all.
conventional method for finding limit can also be used.(though its lengthy but simple and general)
put t=1+h and find limit at h->0+ this will give you right hand limit
put t=1-h and find limit at h->0+ this will give you left hand limit
when you will calculate them you will get limit=- infinity
left hand limit=right hand limit=-infinity
