Kardanoning usuli yordamida kub tenglamasini yechish uchun x^3 + 2x^2 - x - 1 = 0 quyidagi qadamlar: 1-bosqich: Kub tenglamani x^3 + px + q = 0 shakliga aylantiring Biz buni x ni birinchi ikkita haddan va -1 ni oxirgi ikkita haddan ajratib chiqarib bajarishimiz mumkin. Bu bizga quyidagilarni beradi: x^3 + 2x^2 - x - 1 = x^2 - x + 2) - 1^x + 2) = (x^2 - 1) - x ^ ^ + 2) = (x - 1) - x ^ + 1) - x ^ + 2) - x - 1 = 0 shunday yozilishi mumkin: (x - 1) - x ^ + 1) - x ^ - 2 - x ^ - 1 = 0 Kardanoning usuli yordamida x ni yechish uchun 1-bosqich: Kub tenglamani x^3 +
