16-4\left(-1\right)\left(-k+2\right)=0
2 daraja ko‘rsatkichini -4 ga hisoblang va 16 ni qiymatni oling.
16-\left(-4\left(-k+2\right)\right)=0
-4 hosil qilish uchun 4 va -1 ni ko'paytirish.
16+4\left(-k+2\right)=0
-4\left(-k+2\right) ning teskarisi 4\left(-k+2\right) ga teng.
16+4\left(-k\right)+8=0
4 ga -k+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
24+4\left(-k\right)=0
24 olish uchun 16 va 8'ni qo'shing.
4\left(-k\right)=-24

-k=\frac{-24}{4}
Ikki tarafini 4 ga bo‘ling.
-k=-6
-6 ni olish uchun -24 ni 4 ga bo‘ling.
k=6
Ikkala tarafini -1 ga ko‘paytiring.
