    The discriminant is the bit in the quaratic equaiton under the squaer root sign
    that is b^2-4ac
    3 cases
    if
    b^2-4ac>0, there are 2 real roots
    b^2-4ac=0, there is 1 real root
    b^2-4ac<0, there are 2 imaginary roots


    ax^b+bx+c=0

    24x^2+13x
    a=24
    b=13
    13^2-4(24)
    169-96
    73
    discriminatn is 73 A
