Problema 6

Simplify and state excluded values: $\frac{x^{2} - 5 x + 6}{x^{2} - 4}$

$\frac{x - 3}{x + 2}$ , $x is not equal to negative 2$

$\frac{x - 3}{x + 2}$ , for all $x$

$x minus 3$ , $x is not equal to negative 2$

$\frac{x - 3}{x + 2}$ , $x is not equal to 2$ and $x is not equal to negative 2$
