When x = 2, the cube + BX-1 of the algebraic formula ax equals 6. When x equals - 2, what is the value of this formula?
When x = 2, the cube + BX-1 of the algebraic formula ax is equal to 6, that is, the cube + BX = 7 of ax, that is, 8A + 2B = 7. Therefore, when x = - 2, the cube + BX-1 of AX = - 8A - 2b-1 = - (8a + 2b) - 1 = - 7-1 = - 8, that is, when x = - 2, the value of the algebraic formula is - 8
