Hello could someone please help me with this question: Find the limit of 2-x / (x - 1)^2 as x-> 1
What happened to the 2 in the numerator? And if you sub in x=1 for the denominator it equals 0 which is undefined? By the way how did you post the maths equation with the right symbols? I tried copy and pasting the symbols from MS Word, but they didn't come out
