Ikkilamchilar bilan kengayishdan foydalanish qadamlari

Kichik a'zolarni kengaytirish usulidan foydalanib matritsaning aniqlovchisini topish (ko'paytiruvchilarni kengaytirish deb ham nomlanadi).

$$det(\left(\begin{matrix}1&4&6\\-1&2&4\\-5&-4&-3\end{matrix}\right))$$

Kichik a’zolarga kengaytirish uchun birinchi satrning har bir elementini o‘zining kichik a’zosiga ko‘paytiring, qaysiki ana shu elementga ega bo‘lgan satr va ustunni yo‘q qilish orqali yaratilgan 2\times 2 matritsasining maxraji hisoblanadi, so‘ngra elementning joylashuv belgisiga ko‘paytiring.

$$det(\left(\begin{matrix}2&4\\-4&-3\end{matrix}\right))-4det(\left(\begin{matrix}-1&4\\-5&-3\end{matrix}\right))+6det(\left(\begin{matrix}-1&2\\-5&-4\end{matrix}\right))$$

\left(\begin{matrix}a&b\\c&d\end{matrix}\right) 2\times 2 matritsasi uchun, determinant ad-bc.

$$2\left(-3\right)-\left(-4\times 4\right)-4\left(-\left(-3\right)-\left(-5\times 4\right)\right)+6\left(-\left(-4\right)-\left(-5\times 2\right)\right)$$
