Kvadrat ildizini topish bo'yicha qadamlar

3 daraja ko‘rsatkichini 12 ga hisoblang va 1728 ni qiymatni oling.

$$x^{2}=1728-\sqrt{4}$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$x^{2}=1728-2$$

1726 olish uchun 1728 dan 2 ni ayirish.

$$x^{2}=1726$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=\sqrt{1726} x=-\sqrt{1726}$$

Kvadrat tenglamalaridan foydalanish qoidalari

3 daraja ko‘rsatkichini 12 ga hisoblang va 1728 ni qiymatni oling.

$$x^{2}=1728-\sqrt{4}$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$x^{2}=1728-2$$

1726 olish uchun 1728 dan 2 ni ayirish.

$$x^{2}=1726$$

Ikkala tarafdan 1726 ni ayirish.

$$x^{2}-1726=0$$

Ushbu tenglama standart shaklidadir: ax^{2}+bx+c=0. Kvadrat tenglama formulasida, \frac{-b±\sqrt{b^{2}-4ac}}{2a} 1 ni a, 0 ni b va -1726 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-1726\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-1726\right)}}{2}$$

-4 ni -1726 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{6904}}{2}$$

6904 ning kvadrat ildizini chiqarish.

$$x=\frac{0±2\sqrt{1726}}{2}$$

x=\frac{0±2\sqrt{1726}}{2} tenglamasini yeching, bunda ± musbat.

$$x=\sqrt{1726}$$

x=\frac{0±2\sqrt{1726}}{2} tenglamasini yeching, bunda ± manfiy.
