    F = - 2 A x - B

    Explanation:

    The force and potential energy are related by the expression

    F = - dU / dx i ^ - dU / dy j ^ - dU / dz k ^

    Where i ^, j ^, k ^ are the unit vectors on the x and z axis

    The potential they give us is

    U (x) = A x² + B x + C

    Let's calculate the derivatives

    dU / dx = A 2x + B + 0

    The other derivatives are zero because the potential does not depend on these variables.

    Let's calculate the strength

    F = - 2 A x - B
