Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=\sqrt{285} x=-\sqrt{285}$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 285 ni ayirish.

$$x^{2}-285=0$$

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 -285 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-285\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-285\right)}}{2}$$

-4 ni -285 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{1140}}{2}$$

1140 ning kvadrat ildizini chiqarish.

$$x=\frac{0±2\sqrt{285}}{2}$$

x=\frac{0±2\sqrt{285}}{2} tenglamasini yeching, bunda ± musbat.

$$x=\sqrt{285}$$

x=\frac{0±2\sqrt{285}}{2} tenglamasini yeching, bunda ± manfiy.

$$x=-\sqrt{285}$$

Tenglama yechildi.
