Limits problem , i cant solve
Hey everyone again,
I am having trouble with certain limit problems on my exam revision maths booklet , I have attached the questions and answers.
I assume the steps involved to solve questions 6(b), 8(b), 10(a) are as followed: These questions
step 1: Sub in the limits
step 2: if it equals (0/0) we must factorise
step 3: sub final values of factorise.
I cant get the answer. I think it is basic operations I cant do but I am not entirely sure. Please correct me , where I am wrong.
