Qisqa yechim qadamlari

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. -x+8 ni \frac{x+6}{x+6} marotabaga ko'paytirish.

$$\left(\frac{\left(-x+8\right)\left(x+6\right)}{x+6}-\frac{40}{x+6}\right)\left(x+6\right)$$

\frac{\left(-x+8\right)\left(x+6\right)}{x+6} va \frac{40}{x+6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\left(-x+8\right)\left(x+6\right)-40}{x+6}\left(x+6\right)$$

\left(-x+8\right)\left(x+6\right)-40 ichidagi ko‘paytirishlarni bajaring.

$$\frac{-x^{2}-6x+8x+48-40}{x+6}\left(x+6\right)$$

-x^{2}-6x+8x+48-40 kabi iboralarga o‘xshab birlashtiring.

$$\frac{-x^{2}+2x+8}{x+6}\left(x+6\right)$$

x+6 va x+6 ni qisqartiring.

$$-x^{2}+2x+8$$
