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.

$$x^{2}+30x=0$$

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.

$$x=\frac{-30±\sqrt{30^{2}}}{2}$$

30^{2} ning kvadrat ildizini chiqarish.

$$x=\frac{-30±30}{2}$$

x=\frac{-30±30}{2} tenglamasini yeching, bunda ± musbat. -30 ni 30 ga qo'shish.

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

0 ni 2 ga bo'lish.

$$x=0$$

x=\frac{-30±30}{2} tenglamasini yeching, bunda ± manfiy. -30 dan 30 ni ayirish.

$$x=-\frac{60}{2}$$

-60 ni 2 ga bo'lish.

$$x=-30$$

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 -30 ga bo‘ling.

$$x^{2}+30x=x\left(x-\left(-30\right)\right)$$

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

$$x^{2}+30x=x\left(x+30\right)$$
