Kvadrat ildizini topish bo'yicha qadamlar

0 hosil qilish uchun 0 va 2 ni ko'paytirish.

$$x^{2}=12-0x$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$x^{2}=12-0$$

12 olish uchun 12 dan 0 ni ayirish.

$$x^{2}=12$$

Kvadrat tenglamalaridan foydalanish qoidalari

0 hosil qilish uchun 0 va 2 ni ko'paytirish.

$$x^{2}=12-0x$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$x^{2}=12-0$$

12 olish uchun 12 dan 0 ni ayirish.

$$x^{2}=12$$

Ikkala tarafdan 12 ni ayirish.

$$x^{2}-12=0$$

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 -12 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-12\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-12\right)}}{2}$$

-4 ni -12 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{48}}{2}$$

48 ning kvadrat ildizini chiqarish.

$$x=\frac{0±4\sqrt{3}}{2}$$

x=\frac{0±4\sqrt{3}}{2} tenglamasini yeching, bunda ± musbat.

$$x=2\sqrt{3}$$

x=\frac{0±4\sqrt{3}}{2} tenglamasini yeching, bunda ± manfiy.

$$x=-2\sqrt{3}$$

Tenglama yechildi.

$$x=2\sqrt{3} x=-2\sqrt{3}$$
