Question

Напишите ответ и решение

Answer 1

1917х³ - 82х³ - 1999х = 0
1917х² - 82х - 1999 = 0
D = - 82² - 4 * 1917 * (- 1999) = 6724 + 15328332 = 15335056 = 3916²

$x_{1} = \frac{82+3916}{2*1917} = \frac{3998}{3834} \\ \\ x_{2} = \frac{82-3916}{2*1917} = -\frac{3834}{3834} \\ \\ \frac{3998}{3834} -(- \frac{3834}{3834} )= \frac{7832}{3834} = \frac{3916}{1917}$

Ответ: 4) 3916/1917.
