64-16x+x^{2}=x^{2}+6^{2}
\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(8-x\right)^{2} kengaytirilishi uchun ishlating.
64-16x+x^{2}=x^{2}+36
2 daraja ko‘rsatkichini 6 ga hisoblang va 36 ni qiymatni oling.
64-16x+x^{2}-x^{2}=36
Ikkala tarafdan x^{2} ni ayirish.
64-16x=36
0 ni olish uchun x^{2} va -x^{2} ni birlashtirish.
-16x=36-64
Ikkala tarafdan 64 ni ayirish.
-16x=-28
-28 olish uchun 36 dan 64 ni ayirish.
x=\frac{-28}{-16}
Ikki tarafini -16 ga bo‘ling.
x=\frac{7}{4}
\frac{-28}{-16} ulushini -4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
