x uchun yechish

$$x=7\sqrt{2}\approx 9,899494937$$

$$x=-7\sqrt{2}\approx -9,899494937$$

Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

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

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 98 ni ayirish.

$$x^{2}-98=0$$

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 -98 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}-4\left(-98\right)}}{2}$$

0 kvadratini chiqarish.

$$x=\frac{0±\sqrt{-4\left(-98\right)}}{2}$$

-4 ni -98 marotabaga ko'paytirish.

$$x=\frac{0±\sqrt{392}}{2}$$

392 ning kvadrat ildizini chiqarish.

$$x=\frac{0±14\sqrt{2}}{2}$$

x=\frac{0±14\sqrt{2}}{2} tenglamasini yeching, bunda ± musbat.

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

x=\frac{0±14\sqrt{2}}{2} tenglamasini yeching, bunda ± manfiy.

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

Tenglama yechildi.

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