Okay basically i tried to facter out the top part of the rational function but it just doesnt seem corect.

[tex] \lim{x\rightarrow2} [/tex]

[tex] \frac{x^4-16}{x-2} [/tex]

[tex] \lim{x\rightarrow2} [/tex]

[tex] \frac{(x^2+4)(x^2-4}{X-2} [/tex]

[tex] \lim{x\rightarrow2} \frac{(x+2)(x-2)(x^2-4)}{x-2} [/tex]

[tex] \lim{x\rightarrow2} (x+2)(x^2-4)=0 [/tex]

IS that correct, is it okay to factor out one and cancel?
