1-t^{2}=1\times 0
0 ni olish uchun t va -t ni birlashtirish.
1-t^{2}=0
0 hosil qilish uchun 1 va 0 ni ko'paytirish.
-t^{2}=-1
Ikkala tarafdan 1 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
t^{2}=\frac{-1}{-1}
Ikki tarafini -1 ga bo‘ling.
t^{2}=1
1 ni olish uchun -1 ni -1 ga bo‘ling.
t=1 t=-1
Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.
1-t^{2}=1\times 0
0 ni olish uchun t va -t ni birlashtirish.
1-t^{2}=0
0 hosil qilish uchun 1 va 0 ni ko'paytirish.
-t^{2}+1=0
Bu kabi kvadrat tenglamalarni x^{2} sharti bilan, biroq x shartisiz hamon kvadrat tenglamasidan foydalanib yechish mumkin, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, ular standart formulaga solingandan so'ng: ax^{2}+bx+c=0.
t=\frac{0±\sqrt{0^{2}-4\left(-1\right)}}{2\left(-1\right)}
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 1 ni c bilan almashtiring.
t=\frac{0±\sqrt{-4\left(-1\right)}}{2\left(-1\right)}
0 kvadratini chiqarish.
t=\frac{0±\sqrt{4}}{2\left(-1\right)}
-4 ni -1 marotabaga ko'paytirish.
t=\frac{0±2}{2\left(-1\right)}
4 ning kvadrat ildizini chiqarish.
t=\frac{0±2}{-2}
2 ni -1 marotabaga ko'paytirish.
t=-1
t=\frac{0±2}{-2} tenglamasini yeching, bunda ± musbat. 2 ni -2 ga bo'lish.
t=1
t=\frac{0±2}{-2} tenglamasini yeching, bunda ± manfiy. -2 ni -2 ga bo'lish.
t=-1 t=1
Tenglama yechildi.
