    Lets solve the quadratic equation:

    7x^2 + 2x = 0

    (x) (7x + 2) = 0

    therefore, for this equation to hold we need, either one of these conditions:

    x = 0

    or

    7x + 2 = 0

    from where:

    7x = - 2

    x = - 2/7

    then, we have two solutions for the equation as expected being quadratic.
