\[\lim_{x \rightarrow 2} \left( \frac{ 6 }{ x^2+2x8 } \right)+\left(\frac{ x6 }{ x^24} \right)\]

so I found that \[\lim_{x \rightarrow 2} \left( \frac{ 6 }{ (x+4)(x2) } \right)+\left( \frac{ x6 }{ (x+2)(x2) } \right)\] Now what?????

sorry 1/3. I see the next step in the book but I don't understand how they got to it. I will write it up.

they took the LCM in this step

ok. Can you explain that part to me? I don't seem to get it.

write all the terms in denominator if some term is repeating more then once , just write it one time. like in this case on one side u have (x+4)(x−2) and on other side (x+2)(x−2) so write them all in denominator but (x2) is written twice so u will just write it one time

ok but what about the numerator? How did they get to that part?

nubeerBest ResponseYou've already chosen the best response.1
ok now move back a step and see see what u had in denominator before . u had (x+4)(x−2) right?

nubeerBest ResponseYou've already chosen the best response.1
so you compare the old denominator with new numerator whichever is the common denominator u cancel them and whatever is left u multiply it with numerator

are you getting what i am doing?

yes, so basically you devide the entire equation the the common denoiminator and then solve from there. I think I got it. Let me see if it works out.

\[\lim_{x \rightarrow 2} \left[\left( \frac{ 6 }{ (x+4)(x2) } \right)+\left( \frac{ x6 }{ (x+2)(x2) } \right)\right]\] \[\lim_{x \rightarrow 2} \left[\frac{x+2}{x+2}\left( \frac{ 6 }{ (x+4)(x2) } \right)+\frac{x+4}{x+4}\left( \frac{ x6 }{ (x+2)(x2) } \right)\right]\]
