Answer:
3, 4+(1-√13)/2, 4+(1+√13)/2
Step-by-step explanation:
1/x-2+1/x-3+1/x-4=0
(x-2)(x-3)+(x-2)(x-4)+(x-3)(x-4)=(x-2)(x-3)(x-4)
Lets substitute x-3=y, then we have:
y(y-1)+y(y+1)+(y-1)(y+1)=y(y-1)(y+1)
y^2-y+y^1+y+y^2-1=y(y^2-1)
3y^2=y^3-y
y(y^2-3y-1)=0
y=0, y =(3-√13)/2, y =(3+√13)/2
Finding x:
x=y+3
x=3, x=4+(1-√13)/2, x=4+(1+√13)/2
