Tenglama yechildi.
y^{2}+7=0
7 ni ikki tarafga qo’shing.
y=\frac{0±\sqrt{0^{2}-4\times 7}}{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 7 ni c bilan almashtiring.
y=\frac{0±\sqrt{-4\times 7}}{2}
0 kvadratini chiqarish.
y=\frac{0±\sqrt{-28}}{2}
-4 ni 7 marotabaga ko'paytirish.
y=\frac{0±2\sqrt{7}i}{2}
-28 ning kvadrat ildizini chiqarish.
y=\sqrt{7}i
