It is known that no matter what value x takes, the algebraic formula a (X-2) - 2x + 5 is the same, and the value of a is obtained. Because no matter what value x takes, the value of the algebraic formula a (X-2) - 2x + 5 is the same, so we might as well take x = 0 and get a (X-2) - 2x + 5. That is to say, no matter what value x takes, the value of the algebraic formula a (X-2) - 2x + 5 is equal to - 2A + 5, The values of the algebraic formula ax + 2 / bx-5 are the same, so what kind of equivalence relationship should a and B satisfy. (2) no matter what value x takes, the equation x ^ 3 + MX + 2 = (x + 2) (x ^ 2 + ax + b) always holds, and the value of M can be obtained

(1) according to the materials, when x = 0, (a × 0 + 2) / (B × 0-5) = - 2 / 5, when x = 1, (a × 1 + 2) / (B × 1-5) = (a + 2) / (B-5) ∵ no matter what the value of X is, the value of the algebraic formula is the same
