x-1 = 0
x-1 = 0
x-1 = 0 // + 1
x = 1
x in (-oo:1) U (1:+oo)
(3*x^3-(7*x))/(x-1) = 0
(3*x^3-7*x)/(x-1) = 0
3*x^3-7*x = 0
x*(3*x^2-7) = 0
3*x^2 = 7 // : 3
x^2 = 7/3
x^2 = 7/3 // ^ 1/2
abs(x) = (7/3)^(1/2)
x = (7/3)^(1/2) or x = -(7/3)^(1/2)
x*(x-(7/3)^(1/2))*(x+(7/3)^(1/2)) = 0
(x*(x-(7/3)^(1/2))*(x+(7/3)^(1/2)))/(x-1) = 0
( x+(7/3)^(1/2) )
x+(7/3)^(1/2) = 0 // - (7/3)^(1/2)
x = -(7/3)^(1/2)
( x-(7/3)^(1/2) )
x-(7/3)^(1/2) = 0 // + (7/3)^(1/2)
x = (7/3)^(1/2)
