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.

$$x^{2}-18x=0$$

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.

$$x=\frac{-\left(-18\right)±\sqrt{\left(-18\right)^{2}}}{2}$$

\left(-18\right)^{2} ning kvadrat ildizini chiqarish.

$$x=\frac{-\left(-18\right)±18}{2}$$

-18 ning teskarisi 18 ga teng.

$$x=\frac{18±18}{2}$$

x=\frac{18±18}{2} tenglamasini yeching, bunda ± musbat. 18 ni 18 ga qo'shish.

$$x=\frac{36}{2}$$

36 ni 2 ga bo'lish.

$$x=18$$

x=\frac{18±18}{2} tenglamasini yeching, bunda ± manfiy. 18 dan 18 ni ayirish.

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

0 ni 2 ga bo'lish.

$$x=0$$

ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right) formulasi yordamida amalni hisoblang. x_{1} uchun 18 ga va x_{2} uchun 0 ga bo‘ling.

$$x^{2}-18x=\left(x-18\right)x$$
