Since the root of the corresponding equation (X-2) (x-3) = 0 is 2, 3, the solution set is [2,3] 2 4x ^ 2 + 4x + 1 = (2x + 1) ^ 2 ≥ 0, so the original inequality is equivalent to (2x + 1) ^ 2 = 0, so x = - 1 / 23, (x ^ 2 + 4x-2) / x > 0, the zeros of the molecular denominator are 0, - 2 - √ 6, - 2 + √ 6, so
