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.

$$x^{2}+13x=0$$

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.

$$x=\frac{-13±\sqrt{13^{2}}}{2}$$

13^{2} ning kvadrat ildizini chiqarish.

$$x=\frac{-13±13}{2}$$

x=\frac{-13±13}{2} tenglamasini yeching, bunda ± musbat. -13 ni 13 ga qo'shish.

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

0 ni 2 ga bo'lish.

$$x=0$$

x=\frac{-13±13}{2} tenglamasini yeching, bunda ± manfiy. -13 dan 13 ni ayirish.

$$x=-\frac{26}{2}$$

-26 ni 2 ga bo'lish.

$$x=-13$$

ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right) formulasi yordamida amalni hisoblang. x_{1} uchun 0 ga va x_{2} uchun -13 ga bo‘ling.

$$x^{2}+13x=x\left(x-\left(-13\right)\right)$$

p-\left(-q\right) shaklining barcha amallarigani p+q ga soddalashtiring.

$$x^{2}+13x=x\left(x+13\right)$$
