    Finding solution

    We are given that the equation f(x)=0 has a solution at x=3. Using this information we have to find as many solutions as possible of the equations
    1) 2f(x+5)=0 and 2. \left | f(x) \right |=0

    1. 2f(x+5) = 0 is equivalent to f(x+5) = 0.

    Since you know f(3) = 0, set f(x+5) = f(3).

    This much gives you at least x + 5 = 3; x = -2.

    2. |f(x)| = 0 has the same roots as f(x) = 0.
