Question

.
Selesaikan limit berikut!
[tex] \lim\limits_{x\to 2} \frac{ {x}^{2} - 7x - 10}{x - 2} [/tex]
​

Answer 1

Note :

Mungkin ini + 10 bukan - 10.

> = Tanda panah

lim x > 2 (x^2 - 7x + 10)/(x-2) =

lim x > 2 (x - 5)(x - 2)/(x - 2) =

lim x > 2 x - 5 =

2 - 5 = -3.

Answer 2

Jawaban:

-3

Penjelasan dengan langkah-langkah:

[tex]\begin{aligned}\displaystyle\rm~ \lim\limits_{x\to 2} \frac{ {x}^{2} - 7x + 10}{x - 2} & = \displaystyle\rm~ \lim\limits_{x\to 2}\frac{(x - 5)\cancel{(x - 2)}}{\cancel{x - 2}} \\ \\ & = \displaystyle\rm~\lim\limits_{x\to 2}x - 5 \\ \\ & = \displaystyle\rm~2 - 5 \\ \\ & = \displaystyle\rm~ - 3 \end{aligned}[/tex]
