x^{2}+20=0
20 olish uchun -12 va 32'ni qo'shing.
x^{2}=-20
Ikkala tarafdan 20 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=2\sqrt{5}i x=-2\sqrt{5}i
Tenglama yechildi.
x^{2}+20=0
20 olish uchun -12 va 32'ni qo'shing.
x=\frac{0±\sqrt{0^{2}-4\times 20}}{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 20 ni c bilan almashtiring.
x=\frac{0±\sqrt{-4\times 20}}{2}
0 kvadratini chiqarish.
x=\frac{0±\sqrt{-80}}{2}
-4 ni 20 marotabaga ko'paytirish.
x=\frac{0±4\sqrt{5}i}{2}
-80 ning kvadrat ildizini chiqarish.
x=2\sqrt{5}i
x=\frac{0±4\sqrt{5}i}{2} tenglamasini yeching, bunda ± musbat.
x=-2\sqrt{5}i
x=\frac{0±4\sqrt{5}i}{2} tenglamasini yeching, bunda ± manfiy.
x=2\sqrt{5}i x=-2\sqrt{5}i
Tenglama yechildi.
