Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=\sqrt{74} x=-\sqrt{74}$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 74 ni ayirish.

$$x^{2}-74=0$$

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 -74 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-74\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-74\right)}}{2}$$

-4 ni -74 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{296}}{2}$$

296 ning kvadrat ildizini chiqarish.

$$x=\frac{0±2\sqrt{74}}{2}$$

x=\frac{0±2\sqrt{74}}{2} tenglamasini yeching, bunda ± musbat.

$$x=\sqrt{74}$$

x=\frac{0±2\sqrt{74}}{2} tenglamasini yeching, bunda ± manfiy.

$$x=-\sqrt{74}$$

Tenglama yechildi.

$$x=\sqrt{74} x=-\sqrt{74}$$
