Differential: ① y = (x-1) (2-3x) (2x + 3) ② y = xsquare + 3cos2x ③ y = √ x + X ④ y = xlgx ⑤ y = √ (xsquare + 1) (xsquare - 2) the steps should be detailed
Dy = [(2-3x) (2x + 3) - 3 (x-1) (2x + 3) + 2 (x-1) (2-3x)] DX2. Dy = (2x-6sin2x) DX3. Dy = [1 / 2x ^ (- 1 / 2) + 1] DX4. Dy = [lgx + X / (xln10)] DX = [lgx + 1 / ln10] DX5. Dy = 1 / 2 [(xsquare + 1) (xsquare-2)] ^ (- 1 / 2) [2x (xsquare-2) + 2x (xsquare + 1)] = 1 / 2 [(xsquare + 1) (...)

If the equation | AX-1 | = 2A, (a > 0, a ≠ 1) about X has two unequal real roots, then the value range of real number a is______ .
According to the meaning of the question, the image of the function y = | AX-1 | (a > 0, a ≠ 1) has two different intersections with the straight line y = 2A. When a > 1, 0 < a < 1, 0 < 2A < 1, so a ∈ (0, 12), so the answer is: (0, 12)
