If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x in (-oo:+oo)
y = (x^4)/4 // - (x^4)/4
y-((x^4)/4) = 0
-1/4*x^4 = -y // : -1/4
x^4 = 4*y
x^4 = 4*y // ^ 1/4
abs(x) = 4^(1/4)*y^(1/4)
x = 4^(1/4)*y^(1/4) or x = -(4^(1/4)*y^(1/4))
x in { 4^(1/4)*y^(1/4), -(4^(1/4)*y^(1/4)) }
