Solve the equation 4x-2x + 2-12 = 0

Let 2x = t (T > 0), then the original equation can be reduced to: t2-4t-12 = 0, and the solution set of the original equation is {x | x = 1 + log23}

The solution equation: (x2-x) 2-4 (x2-x) - 12 = 0

The deformation of the equation is as follows: (x2-x-6) (x2-x + 2) = 0, then x2-x-6 = 0 or x2-x + 2 = 0 (the equation has no solution), and the solution is X1 = 3, X2 = - 2
