Lim (x^2-x+6)/(x-2) when x goes to 2. How to solve it?

OpenStudy (anonymous):

factorise first

OpenStudy (jpsmarinho):

But the equation of the numeiator has complex roots.

OpenStudy (anonymous):

what is the answer? is it equal to 3?

OpenStudy (jpsmarinho):

No, the answer is that the lim not exist. But how I found this solution?

OpenStudy (anonymous):

just assign the value of x in the limit..

OpenStudy (anonymous):

\[\lim_{x \rightarrow 2} (2^2-2+6)/(2-2)\]

OpenStudy (anonymous):

\[= \lim_{x \rightarrow 2} 8/0 = \infty \]

OpenStudy (jpsmarinho):

But the 0 on the denominator proof that has no limit?

OpenStudy (jpsmarinho):

Aha right

OpenStudy (anonymous):

yep..the limit is does not exists when it is equal to infinity

OpenStudy (jpsmarinho):

Males sense. Thanks!

OpenStudy (anonymous):

For your information, any number divided by 0 is equal to infinity. So, there is no limit. Tq
