Kvadrat tenglamalaridan foydalanish qoidalari

Kvadrat koʻp tenglama bu orqali hisoblanadi: ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right), bu yerda x_{1} va x_{2} ax^{2}+bx+c=0 kvadrat tenglamaning yechimlari.

$$m^{2}-3m=0$$

ax^{2}+bx+c=0 shaklidagi barcha tenglamalarni kvadrat formulasi bilan yechish mumkin: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Kvadrat formula ikki yechmni taqdim qiladi, biri ± qo'shish bo'lganda, va ikkinchisi ayiruv bo'lganda.

$$m=\frac{-\left(-3\right)±\sqrt{\left(-3\right)^{2}}}{2}$$

\left(-3\right)^{2} ning kvadrat ildizini chiqarish.

$$m=\frac{-\left(-3\right)±3}{2}$$

-3 ning teskarisi 3 ga teng.

$$m=\frac{3±3}{2}$$

m=\frac{3±3}{2} tenglamasini yeching, bunda ± musbat. 3 ni 3 ga qo'shish.

$$m=\frac{6}{2}$$

6 ni 2 ga bo'lish.

$$m=3$$

m=\frac{3±3}{2} tenglamasini yeching, bunda ± manfiy. 3 dan 3 ni ayirish.

$$m=\frac{0}{2}$$

0 ni 2 ga bo'lish.

$$m=0$$

ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right) formulasi yordamida amalni hisoblang. x_{1} uchun 3 ga va x_{2} uchun 0 ga bo‘ling.

$$m^{2}-3m=\left(m-3\right)m$$

Baholash

$$m\left(m-3\right)$$
