\left(x-1\right)\times 5+\left(x-1\right)\left(x+1\right)\left(-1\right)=\left(x+1\right)\left(10-x\right)
x qiymati -1,1 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x-1\right)\left(x+1\right) ga, x+1,x-1 ning eng kichik karralisiga ko‘paytiring.
5x-5+\left(x-1\right)\left(x+1\right)\left(-1\right)=\left(x+1\right)\left(10-x\right)
x-1 ga 5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x-5+\left(x^{2}-1\right)\left(-1\right)=\left(x+1\right)\left(10-x\right)
x-1 ga x+1 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
5x-5-x^{2}+1=\left(x+1\right)\left(10-x\right)
x^{2}-1 ga -1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x-4-x^{2}=\left(x+1\right)\left(10-x\right)
-4 olish uchun -5 va 1'ni qo'shing.
5x-4-x^{2}=9x-x^{2}+10
x+1 ga 10-x ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
5x-4-x^{2}-9x=-x^{2}+10
Ikkala tarafdan 9x ni ayirish.
-4x-4-x^{2}=-x^{2}+10
-4x ni olish uchun 5x va -9x ni birlashtirish.
-4x-4-x^{2}+x^{2}=10
x^{2} ni ikki tarafga qo’shing.
-4x-4=10
0 ni olish uchun -x^{2} va x^{2} ni birlashtirish.
-4x=10+4
4 ni ikki tarafga qo’shing.
-4x=14
14 olish uchun 10 va 4'ni qo'shing.
x=\frac{14}{-4}
Ikki tarafini -4 ga bo‘ling.
x=-\frac{7}{2}
\frac{14}{-4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
