i mean is it cube root of unity ? or imaginary number i or something else ? if not, then u just said its variable, so x^4+x^2 can't equal 1.

x^4 +x^2=1 => => x^4 +x^2 1 = 0 => (x +0.786)*(x 0.786)*(x^2 +1.618) = 0 Real solutions: Root 1: 0.786 Root 2: 0.786 Complex roots: Root 3: 0+1.272 * i Root 4: 01.272 * i

so for any of the 4 values of x we found above, u can prove that x^4+x^2= 1

solving for x in x^4+x^2=1 means ginding vales of x for which x^4+x^2 equals 1 so, for the 4 values we found, x^4+x^2 will equal 1.
