25-a^{2}=41-\left(64-16a+a^{2}\right)
\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(8-a\right)^{2} kengaytirilishi uchun ishlating.
25-a^{2}=41-64+16a-a^{2}
64-16a+a^{2} teskarisini topish uchun har birining teskarisini toping.
25-a^{2}=-23+16a-a^{2}
-23 olish uchun 41 dan 64 ni ayirish.
25-a^{2}-16a=-23-a^{2}
Ikkala tarafdan 16a ni ayirish.
25-a^{2}-16a+a^{2}=-23
a^{2} ni ikki tarafga qo’shing.
25-16a=-23
0 ni olish uchun -a^{2} va a^{2} ni birlashtirish.
-16a=-23-25
Ikkala tarafdan 25 ni ayirish.
-16a=-48
-48 olish uchun -23 dan 25 ni ayirish.
a=\frac{-48}{-16}
Ikki tarafini -16 ga bo‘ling.
a=3
3 ni olish uchun -48 ni -16 ga bo‘ling.
