196-x^{2}=\left(x-17\right)\left(76-x\right)
Hisoblang: \left(14+x\right)\left(14-x\right). Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}. 14 kvadratini chiqarish.
196-x^{2}=93x-x^{2}-1292
x-17 ga 76-x ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
196-x^{2}-93x=-x^{2}-1292
Ikkala tarafdan 93x ni ayirish.
196-x^{2}-93x+x^{2}=-1292
x^{2} ni ikki tarafga qo’shing.
196-93x=-1292
0 ni olish uchun -x^{2} va x^{2} ni birlashtirish.
-93x=-1292-196
Ikkala tarafdan 196 ni ayirish.
-93x=-1488
-1488 olish uchun -1292 dan 196 ni ayirish.
x=\frac{-1488}{-93}
Ikki tarafini -93 ga bo‘ling.
x=16
16 ni olish uchun -1488 ni -93 ga bo‘ling.
