РЕШИТЕ УРАВНЕНИЕ (х^2-4)(\х\-7)(1/2х-19)=0

(х^2-4) (|х|-7)(1/2х-19)=0 (x^2-4)=0       или    |x|-7=0               или   1/2х-19=0 (х-2) (х+2)=0            Если |x|=x, то               1/2х=19 х=2                             х-7=0                              0,5х=19 х=-2                            х=7                                  х= 38                                    Если |x|=-x, то                                                 -х-7=0                                    -х=7                                     х=-7 Ответ: 2, -2, 38, если |x|=x, то  х=7, если |x|=-x, то х=-7
