Question

〖lim〗(x→1 )⁡〖(x2-1)/(x-1)〗

Answer 1

It is looking a bit weird to me.

Answer 2

I will try to guess what I'm seeing...
\[\lim_{x \rightarrow 1}\frac{x^2-1}{x-1}\]?

Answer 3

If that is the problem, here is a hint to the problem:
Factor the top and then cancel a common factor.

Answer 4

ok ((

Answer 5

what do you get when you factor x^2-1?

Answer 6

i don't no

Answer 7

a^2-b^2=(a-b)(a+b)

Answer 8

\[\left( \times +1 \right)\]

Answer 9

x+1 is what you get when the (x-1)'s cancel

Answer 10

So since x+1 is continuous at x=1 you can easily find the limit now but just plugging in 1

Answer 11

(x+1)(x-1)/(x-1)= (x+1)

Answer 12

right

Answer 13

But you to take care of the limit part now

Answer 14

yaay thank u (:
