Homework Statement
Evaluate the limit below indicating the appropriate Limit Law(s) implemented.
[tex]\lim_{x\rightarrow 0.5}\frac{2x^2+5x-3}{6x^2-7x+2}[/itex]
2. The attempt at a solution
[tex]\lim_{x\rightarrow 0.5}\frac{2x^2+5x-3}{6x^2-7x+2}=\lim_{x\rightarrow 0.5}\frac{2(x-0.5)(x+3)}{6(x-0.5)(x-(2/3))}=\lim_{x\rightarrow 0.5}\frac{2(x+3)}{6(x-(2/3))}=-7[/itex]
So would I be required to state anything when I can out the (x-0.5) factor?
(PS, I'm doing Real Analysis and have learned about proving limits from first principles but I'm now trying to learn about using shortcuts by referencing theorems.)
