(n-6)(n-1/2) eching

$$( n - 6 ) ( n - \frac { 1 } { 2 } )$$

Baholash

$$n^{2}-\frac{13n}{2}+3$$

Yechim qadamlari

n-6 ifodaning har bir elementini n-\frac{1}{2} ifodaning har bir elementiga ko‘paytirish orqali taqsimot qonuni xususiyatlarini qo‘llash mumkin.

$$n^{2}+n\left(-\frac{1}{2}\right)-6n-6\left(-\frac{1}{2}\right)$$

-\frac{13}{2}n ni olish uchun n\left(-\frac{1}{2}\right) va -6n ni birlashtirish.

$$n^{2}-\frac{13}{2}n-6\left(-\frac{1}{2}\right)$$

-6\left(-\frac{1}{2}\right) ni yagona kasrga aylantiring.

$$n^{2}-\frac{13}{2}n+\frac{-6\left(-1\right)}{2}$$

6 hosil qilish uchun -6 va -1 ni ko'paytirish.

$$n^{2}-\frac{13}{2}n+\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.

$$n^{2}-\frac{13}{2}n+3$$
