Решите уравнение 2х^3-х(х^2-6)-3(2х-1)-30=0 ^-cтепень

2x³-x(x²-6)-3(2x-1)-30=0 2x³-x³+6x-6x+3-30=0 x³-27=0 x³=27 x=∛27 x=3

Найдем производную этой функции по формуле производной частного, получим у¹=((2х-3)(х-²-3х))/(х-4)²=(х²-8х+12)/(х-4)² разложим х²-8х+12=0 d=64-48=16=4² x₁=(8-4)/2=2 x₂=(8+4)/2=6 x²-8x+12=(x-2)(x-6)=0 точки экстремума определяются ихз условия, что производная в них равна нулю, значит х=2 и х=6 точки х=2 и х=6 разбивают числовую прямую на три интервала (-∞; 2); (2; 6) и (6; +∞) проверив знаки производной в каждом интервале, мы увидим, что в первом и третьем  интервалах производная положительна, во втором отрицательна, значит х=2 - точка максимума, х=6 -  точка минимума функции
