Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$a=\sqrt{3} a=-\sqrt{3}$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 3 ni ayirish.

$$a^{2}-3=0$$

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 -3 ni c bilan almashtiring.

$$a=\frac{0±\sqrt{0^{2}-4\left(-3\right)}}{2}$$

0 kvadratini chiqarish.

$$a=\frac{0±\sqrt{-4\left(-3\right)}}{2}$$

-4 ni -3 marotabaga ko'paytirish.

$$a=\frac{0±\sqrt{12}}{2}$$

12 ning kvadrat ildizini chiqarish.

$$a=\frac{0±2\sqrt{3}}{2}$$

a=\frac{0±2\sqrt{3}}{2} tenglamasini yeching, bunda ± musbat.

$$a=\sqrt{3}$$

a=\frac{0±2\sqrt{3}}{2} tenglamasini yeching, bunda ± manfiy.

$$a=-\sqrt{3}$$

Tenglama yechildi.

$$a=\sqrt{3} a=-\sqrt{3}$$
