\frac{z-5}{\left(z-9\right)\left(z+9\right)}-\frac{6-z}{\left(z-9\right)\left(-z-9\right)}

Faktor: z^{2}-81. Faktor: 81-z^{2}.

\frac{z-5}{\left(z-9\right)\left(z+9\right)}-\frac{-\left(6-z\right)}{\left(z-9\right)\left(z+9\right)}

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. \left(z-9\right)\left(z+9\right) va \left(z-9\right)\left(-z-9\right) ning eng kichik umumiy karralisi \left(z-9\right)\left(z+9\right). \frac{6-z}{\left(z-9\right)\left(-z-9\right)} ni \frac{-1}{-1} marotabaga ko'paytirish.

\frac{z-5-\left(-\left(6-z\right)\right)}{\left(z-9\right)\left(z+9\right)}

\frac{z-5}{\left(z-9\right)\left(z+9\right)} va \frac{-\left(6-z\right)}{\left(z-9\right)\left(z+9\right)} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

\frac{z-5+6-z}{\left(z-9\right)\left(z+9\right)}

z-5-\left(-\left(6-z\right)\right) ichidagi ko‘paytirishlarni bajaring.

\frac{1}{\left(z-9\right)\left(z+9\right)}

z-5+6-z kabi iboralarga o‘xshab birlashtiring.

\frac{1}{z^{2}-81}

\left(z-9\right)\left(z+9\right) ni kengaytirish.
