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.

$$y^{2}-9y=0$$

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.

$$y=\frac{-\left(-9\right)±\sqrt{\left(-9\right)^{2}}}{2}$$

\left(-9\right)^{2} ning kvadrat ildizini chiqarish.

$$y=\frac{-\left(-9\right)±9}{2}$$

-9 ning teskarisi 9 ga teng.

$$y=\frac{9±9}{2}$$

y=\frac{9±9}{2} tenglamasini yeching, bunda ± musbat. 9 ni 9 ga qo'shish.

$$y=\frac{18}{2}$$

18 ni 2 ga bo'lish.

$$y=9$$

y=\frac{9±9}{2} tenglamasini yeching, bunda ± manfiy. 9 dan 9 ni ayirish.

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

0 ni 2 ga bo'lish.

$$y=0$$

ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right) formulasi yordamida amalni hisoblang. x_{1} uchun 9 ga va x_{2} uchun 0 ga bo‘ling.

$$y^{2}-9y=\left(y-9\right)y$$

Baholash

$$y\left(y-9\right)$$
