x(x-1)(x-2)(x-3)<3*4*5*6

楼上的没考虑全啊,
除了 x<6 ,还应该有x>-3
x(x-1)(x-2)(x-3)<3*4*5*6
x(x-1)(x-2)(x-3)<(6-3)*(6-2)*(6-1)*6
x<6
x(x-1)(x-2)(x-3)<3*4*5*6
x(x-1)(x-2)(x-3)<(-3)*(-4)*(-5)*(-6)
x(x-1)(x-2)(x-3)<(-3)(-3-1)(-3-2)(-3-3)
x>-3
综上:-3<x<6

x(x-1)(x-2)(x-3)<3*4*5*6
x(x-1)(x-2)(x-3)<(6-3)(6-2)(6-1)6
x<6
