Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.
x^{2}-162=0
Ikkala tarafdan 162 ni ayirish.
x=\frac{0±\sqrt{0^{2}-4\left(-162\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 -162 ni c bilan almashtiring.
x=\frac{0±\sqrt{-4\left(-162\right)}}{2}
0 kvadratini chiqarish.
x=\frac{0±\sqrt{648}}{2}
-4 ni -162 marotabaga ko'paytirish.
x=\frac{0±18\sqrt{2}}{2}
648 ning kvadrat ildizini chiqarish.
x=9\sqrt{2}
x=\frac{0±18\sqrt{2}}{2} tenglamasini yeching, bunda ± musbat.
x=-9\sqrt{2}
x=\frac{0±18\sqrt{2}}{2} tenglamasini yeching, bunda ± manfiy.
x=9\sqrt{2} x=-9\sqrt{2}
Tenglama yechildi.
