\left(x-2\right)\left(11x-18\right)\left(x+1\right)+\left(x-1\right)\left(11x-18\right)\left(x+2\right)=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
x qiymati 1,\frac{18}{11},2 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x-2\right)\left(x-1\right)\left(11x-18\right) ga, x-1,x-2,11x-18 ning eng kichik karralisiga ko‘paytiring.
\left(11x^{2}-40x+36\right)\left(x+1\right)+\left(x-1\right)\left(11x-18\right)\left(x+2\right)=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
x-2 ga 11x-18 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
11x^{3}-29x^{2}-4x+36+\left(x-1\right)\left(11x-18\right)\left(x+2\right)=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
11x^{2}-40x+36 ga x+1 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
11x^{3}-29x^{2}-4x+36+\left(11x^{2}-29x+18\right)\left(x+2\right)=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
x-1 ga 11x-18 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
11x^{3}-29x^{2}-4x+36+11x^{3}-7x^{2}-40x+36=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
11x^{2}-29x+18 ga x+2 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
22x^{3}-29x^{2}-4x+36-7x^{2}-40x+36=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
22x^{3} ni olish uchun 11x^{3} va 11x^{3} ni birlashtirish.
22x^{3}-36x^{2}-4x+36-40x+36=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
-36x^{2} ni olish uchun -29x^{2} va -7x^{2} ni birlashtirish.
22x^{3}-36x^{2}-44x+36+36=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
-44x ni olish uchun -4x va -40x ni birlashtirish.
22x^{3}-36x^{2}-44x+72=\left(x-2\right)\left(x-1\right)\left(22x+30\right)
72 olish uchun 36 va 36'ni qo'shing.
22x^{3}-36x^{2}-44x+72=\left(x^{2}-3x+2\right)\left(22x+30\right)
x-2 ga x-1 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
22x^{3}-36x^{2}-44x+72=22x^{3}-36x^{2}-46x+60
x^{2}-3x+2 ga 22x+30 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
22x^{3}-36x^{2}-44x+72-22x^{3}=-36x^{2}-46x+60
Ikkala tarafdan 22x^{3} ni ayirish.
-36x^{2}-44x+72=-36x^{2}-46x+60
0 ni olish uchun 22x^{3} va -22x^{3} ni birlashtirish.

2x=-12
-12 olish uchun 60 dan 72 ni ayirish.
x=\frac{-12}{2}
Ikki tarafini 2 ga bo‘ling.
x=-6
-6 ni olish uchun -12 ni 2 ga bo‘ling.
