x^{2}=5-2
Ikkala tarafdan 2 ni ayirish.
x^{2}=3
3 olish uchun 5 dan 2 ni ayirish.
x=\sqrt{3} x=-\sqrt{3}
Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.
x^{2}+2-5=0
Ikkala tarafdan 5 ni ayirish.
x^{2}-3=0
-3 olish uchun 2 dan 5 ni ayirish.
x=\frac{0±\sqrt{0^{2}-4\left(-3\right)}}{2}
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 -3 ni c bilan almashtiring.
x=\frac{0±\sqrt{-4\left(-3\right)}}{2}
0 kvadratini chiqarish.
x=\frac{0±\sqrt{12}}{2}
-4 ni -3 marotabaga ko'paytirish.
x=\frac{0±2\sqrt{3}}{2}
12 ning kvadrat ildizini chiqarish.
x=\sqrt{3}
x=\frac{0±2\sqrt{3}}{2} tenglamasini yeching, bunda ± musbat.
x=-\sqrt{3}
x=\frac{0±2\sqrt{3}}{2} tenglamasini yeching, bunda ± manfiy.
x=\sqrt{3} x=-\sqrt{3}
Tenglama yechildi.
