3mn/m-n+m-2n= eching

$$\frac { 3 m n } { m - n } + m - 2 n =$$

Baholash

$$\frac{m^{2}+2n^{2}}{m-n}$$

Qisqa yechim qadamlari

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. m-2n ni \frac{m-n}{m-n} marotabaga ko'paytirish.

$$\frac{3mn}{m-n}+\frac{\left(m-2n\right)\left(m-n\right)}{m-n}$$

\frac{3mn}{m-n} va \frac{\left(m-2n\right)\left(m-n\right)}{m-n} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3mn+\left(m-2n\right)\left(m-n\right)}{m-n}$$

3mn+\left(m-2n\right)\left(m-n\right) ichidagi ko‘paytirishlarni bajaring.

$$\frac{3mn+m^{2}-mn-2nm+2n^{2}}{m-n}$$

3mn+m^{2}-mn-2nm+2n^{2} kabi iboralarga o‘xshab birlashtiring.

$$\frac{2n^{2}+m^{2}}{m-n}$$

m ga nisbatan hosilani topish

$$\frac{m^{2}-2mn-2n^{2}}{\left(m-n\right)^{2}}$$
