-2,3(х+5)(2х-7)х(4-1/3х)=0

Пошаговое объяснение:

-2,3 (х + 5) (2х - 7) х (4 - 1/3х) = 0

(-2,3х - 11,5) (2x - 7) (4x - 1/3) = 0

(-23/10x - 11,5) (2x - 7) (4x - 1/3) = 0

(-23/10x - 23/2) (2x - 7) (4x - 1/3) = 0

-23/10x - 23/2 = 0

2x - 7 = 0

4x - 1/3 = 0

x = -5

x = 7/2 = 3 1/2 = 3,5

x = 1/12

Значит, х1 = -5, х2= 1/12, х3 = 3,5
