lim x➡-1 x²-x-2 / (x+1)²

[tex]lim \: x = - 1 \: \: \: \frac{x {}^{2} - x - 2}{( x + 1) {}^{2} } \\ = \frac{x {}^{2} - x - 2 }{x {}^{2} + 1 {}^{2} } \\ = \frac{ - x - 2}{1} [/tex]
jadi jika Limit mendekati -1 maka X=-1
[tex] \frac{ - x - 2}{1} = \frac{ - 1( - 1) - 2}{1} \\ = 1 - 2 \\ = - 1[/tex]
Moga membantu :)
