If x = 1, the value of the algebraic formula ax ^ 2 + BX + 1 is 5. When x = - 1, the value of the algebraic formula ax ^ 3 + BX + 1 is obtained The first is ax ^ 2, the second is ax ^ 3

If x = 1, the value of the algebraic formula ax ^ 2 + BX + 1 is 5. When x = - 1, the value of the algebraic formula ax ^ 3 + BX + 1 is obtained The first is ax ^ 2, the second is ax ^ 3

-3
X = 1
A + B + 1 = 5 means a + B = 4
When x = - 1, the algebraic expression is - A-B + 1
That is - (a + b) + 1 = - 3
That's right. That's it
