Rossi46 Vamos lá .

$\lim_{x \to \ \frac{1}{2} } \frac{4 x^{2} -1}{2x-1} _$ = $\lim_{x \to \ \frac{1}{2} } \frac{(2x+1).(2x-1)}{2x-1} _$

$\lim_{x \to \ \frac{1}{2} } \frac{4 x^{2} -1}{2x-1} _$ = $\lim_{x \to \ \frac{1}{2} } 2x+1_$

$\lim_{n \to \ \frac{1}{2} } \frac{4 x^{2} -1}{2x-1} _$ = $2. \frac{1}{2} + 1 = 2$
