Kvadrat ildizini topish bo'yicha qadamlar

28 olish uchun 64 dan 36 ni ayirish.

$$c^{2}=28$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$c=2\sqrt{7} c=-2\sqrt{7}$$

Kvadrat tenglamalaridan foydalanish qoidalari

28 olish uchun 64 dan 36 ni ayirish.

$$c^{2}=28$$

Ikkala tarafdan 28 ni ayirish.

$$c^{2}-28=0$$

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 -28 ni c bilan almashtiring.

$$c=\frac{0±\sqrt{0^{2}-4\left(-28\right)}}{2}$$

0 kvadratini chiqarish.

$$c=\frac{0±\sqrt{-4\left(-28\right)}}{2}$$

-4 ni -28 marotabaga ko'paytirish.

$$c=\frac{0±\sqrt{112}}{2}$$

112 ning kvadrat ildizini chiqarish.

$$c=\frac{0±4\sqrt{7}}{2}$$

c=\frac{0±4\sqrt{7}}{2} tenglamasini yeching, bunda ± musbat.

$$c=2\sqrt{7}$$

c=\frac{0±4\sqrt{7}}{2} tenglamasini yeching, bunda ± manfiy.

$$c=-2\sqrt{7}$$

Tenglama yechildi.

$$c=2\sqrt{7} c=-2\sqrt{7}$$
