t^{2}+3t+2=0
x^{2} uchun t ni almashtiring.
t=\frac{-3±\sqrt{3^{2}-4\times 1\times 2}}{2}
ax^{2}+bx+c=0 shaklidagi barcha tenglamalarni bu formula bilan yechish mumkin: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Kvadrat tenglamada a uchun 1 ni, b uchun 3 ni va c uchun 2 ni ayiring.
t=\frac{-3±1}{2}
Hisoblarni amalga oshiring.
t=-1 t=-2
t=\frac{-3±1}{2} tenglamasini ± plus va ± minus boʻlgan holatida ishlang.
x\in \emptyset
x=t^{2} boʻlganda, yechimlar musbat t uchun x=±\sqrt{t} hisoblanishi orqali olinadi.
