    The general form of a quadratic equation is that which is expressed in a form,

    ax² + bx + c = 0

    To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,

    3x² + 50x - 70 = 0

    The value of b is therefore 50 and the answer is the second choice.
