Question

Calcule o valor de lim┬(x→-1)⁡〖(〖6x〗^2-4x+2)/(〖6x〗^2-4x)〗, para x = -1

Answer 1

:)

$\lim_{x \to -1} \frac{6x^2-4x+2}{6x^2-4x} \\ \\ \lim_{x \to -1} \frac{6(-1)^2-4(-1)+2}{6(-1)^2-4(-1)} \\ \\ \lim_{x \to -1} \frac{6+4+2}{6+4} \\ \\ \lim_{x \to -1} \frac{12}{10} \\ \\ \lim_{x \to -1} \frac{6}{5}$
