Answer 1

Răspuns:

Explicație pas cu pas:

$\frac{3x-2}{x^{2} } = \frac{3*(-2)-2}{(-2)^{2} } = \frac{-6-2}{4} = \frac{-8}{4} = -2$

$\frac{x+1}{x^{2} +x+1} = \frac{-2+1}{(-2)^{2} + (-2)+1} = \frac{-1}{4-2+1} = \frac{-1}{3}$

$\frac{x-2}{x^{2} -2x-2} = \frac{-2-2}{(-2)^{2} - 2* (-2)-2} = \frac{-4}{4+4-2} = \frac{-4}{6} = \frac{-2}{3}$
