t^{2}-8t+16=\left(t+4\right)^{2}+32
\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(t-4\right)^{2} kengaytirilishi uchun ishlating.
t^{2}-8t+16=t^{2}+8t+16+32
\left(a+b\right)^{2}=a^{2}+2ab+b^{2} binom teoremasini \left(t+4\right)^{2} kengaytirilishi uchun ishlating.
t^{2}-8t+16=t^{2}+8t+48
48 olish uchun 16 va 32'ni qo'shing.
t^{2}-8t+16-t^{2}=8t+48
Ikkala tarafdan t^{2} ni ayirish.
-8t+16=8t+48
0 ni olish uchun t^{2} va -t^{2} ni birlashtirish.
-8t+16-8t=48
Ikkala tarafdan 8t ni ayirish.
-16t+16=48
-16t ni olish uchun -8t va -8t ni birlashtirish.
-16t=48-16
Ikkala tarafdan 16 ni ayirish.
-16t=32
32 olish uchun 48 dan 16 ni ayirish.
t=\frac{32}{-16}
Ikki tarafini -16 ga bo‘ling.
t=-2
-2 ni olish uchun 32 ni -16 ga bo‘ling.
