Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$xx=324$$

x^{2} hosil qilish uchun x va x ni ko'paytirish.

$$x^{2}=324$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=18 x=-18$$

Kvadrat tenglamalaridan foydalanish qoidalari

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$xx=324$$

x^{2} hosil qilish uchun x va x ni ko'paytirish.

$$x^{2}=324$$

Ikkala tarafdan 324 ni ayirish.

$$x^{2}-324=0$$

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 -324 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-324\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-324\right)}}{2}$$

-4 ni -324 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{1296}}{2}$$

1296 ning kvadrat ildizini chiqarish.

$$x=\frac{0±36}{2}$$

x=\frac{0±36}{2} tenglamasini yeching, bunda ± musbat. 36 ni 2 ga bo'lish.

$$x=18$$

x=\frac{0±36}{2} tenglamasini yeching, bunda ± manfiy. -36 ni 2 ga bo'lish.

$$x=-18$$

Tenglama yechildi.

$$x=18 x=-18$$
