b uchun yechish
b=-\left(2a^{2}+c\right)
a uchun yechish
a=\frac{\sqrt{-2b-2c}}{2}
a=-\frac{\sqrt{-2b-2c}}{2}\text{, }b\leq -c
Baham ko'rish
Klipbordga nusxa olish
2b+2c=-4a^{2}
Ikkala tarafdan 4a^{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
2b=-4a^{2}-2c
Ikkala tarafdan 2c ni ayirish.
\frac{2b}{2}=\frac{-4a^{2}-2c}{2}
Ikki tarafini 2 ga bo‘ling.
b=\frac{-4a^{2}-2c}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
b=-2a^{2}-c
-4a^{2}-2c ni 2 ga bo'lish.
