    axis of symetry can be found using -b/2a so we can set that equal to -3

    we know that one part of the equation is (x-4)

    The axis of symmetry indicates that the zeroes of the function in relation to the vertex of the parabola (represented by the axis of symmetry) lie equidistant to the vertex. That is how @inkyvoyd knew the other zero was at -10.
