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.

$$m^{2}-8m-10=0$$

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.

$$m=\frac{-\left(-8\right)±\sqrt{\left(-8\right)^{2}-4\left(-10\right)}}{2}$$

-8 kvadratini chiqarish.

$$m=\frac{-\left(-8\right)±\sqrt{64-4\left(-10\right)}}{2}$$

-4 ni -10 marotabaga ko'paytirish.

$$m=\frac{-\left(-8\right)±\sqrt{64+40}}{2}$$

64 ni 40 ga qo'shish.

$$m=\frac{-\left(-8\right)±\sqrt{104}}{2}$$

104 ning kvadrat ildizini chiqarish.

$$m=\frac{-\left(-8\right)±2\sqrt{26}}{2}$$

-8 ning teskarisi 8 ga teng.

$$m=\frac{8±2\sqrt{26}}{2}$$

m=\frac{8±2\sqrt{26}}{2} tenglamasini yeching, bunda ± musbat. 8 ni 2\sqrt{26} ga qo'shish.

$$m=\frac{2\sqrt{26}+8}{2}$$

8+2\sqrt{26} ni 2 ga bo'lish.

$$m=\sqrt{26}+4$$

m=\frac{8±2\sqrt{26}}{2} tenglamasini yeching, bunda ± manfiy. 8 dan 2\sqrt{26} ni ayirish.

$$m=\frac{8-2\sqrt{26}}{2}$$

8-2\sqrt{26} ni 2 ga bo'lish.

$$m=4-\sqrt{26}$$

ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right) formulasi yordamida amalni hisoblang. x_{1} uchun 4+\sqrt{26} ga va x_{2} uchun 4-\sqrt{26} ga bo‘ling.

$$m^{2}-8m-10=\left(m-\left(\sqrt{26}+4\right)\right)\left(m-\left(4-\sqrt{26}\right)\right)$$
