x^2div3*2=6 eching

$${ x }^{ 2 } \div 3 \times 2=6$$

x uchun yechish

$$x=3$$

$$x=-3$$

Kvadratlar farqidan foydalangan qadamlar

Ikki tarafini 2 ga bo‘ling.

$$\frac{x^{2}}{3}=\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.

$$\frac{x^{2}}{3}=3$$

Ikkala tarafini 3 ga ko‘paytiring.

$$x^{2}=3\times 3$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$x^{2}=9$$

Ikkala tarafdan 9 ni ayirish.

$$x^{2}-9=0$$

Hisoblang: x^{2}-9. x^{2}-9 ni x^{2}-3^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).

$$\left(x-3\right)\left(x+3\right)=0$$

Tenglamani yechish uchun x-3=0 va x+3=0 ni yeching.

$$x=3 x=-3$$

Kvadrat ildizini topish bo'yicha qadamlar

Ikki tarafini 2 ga bo‘ling.

$$\frac{x^{2}}{3}=\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.

$$\frac{x^{2}}{3}=3$$

Ikkala tarafini 3 ga ko‘paytiring.

$$x^{2}=3\times 3$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$x^{2}=9$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=3 x=-3$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikki tarafini 2 ga bo‘ling.

$$\frac{x^{2}}{3}=\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.

$$\frac{x^{2}}{3}=3$$

Ikkala tarafini 3 ga ko‘paytiring.

$$x^{2}=3\times 3$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$x^{2}=9$$

Ikkala tarafdan 9 ni ayirish.

$$x^{2}-9=0$$

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 -9 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-9\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-9\right)}}{2}$$

-4 ni -9 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{36}}{2}$$

36 ning kvadrat ildizini chiqarish.

$$x=\frac{0±6}{2}$$

x=\frac{0±6}{2} tenglamasini yeching, bunda ± musbat. 6 ni 2 ga bo'lish.

$$x=3$$

x=\frac{0±6}{2} tenglamasini yeching, bunda ± manfiy. -6 ni 2 ga bo'lish.

$$x=-3$$

Tenglama yechildi.

$$x=3 x=-3$$
