x in (-oo:+oo)
133*x-((78/133)*x)-(78*x) = x^5 // - x^5
133*x-x^5-((78/133)*x)-(78*x) = 0
133*x-x^5+(-78/133)*x-78*x = 0
7237/133*x-x^5 = 0
x*(7237/133-x^4) = 0
-1*x^4 = -7237/133 // : -1
x^4 = 7237/133
x^4 = 7237/133 // ^ 1/4
abs(x) = (7237/133)^(1/4)
x = (7237/133)^(1/4) or x = -(7237/133)^(1/4)
x = 0
x = 0
x in { (7237/133)^(1/4), -(7237/133)^(1/4), 0 }
