    b = 3

    c = 7

    quadratic formula:

    [tex]x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]     (+/- is this ±)

    plug in the numbers into the variables

    [tex]x = \frac{-3+/-\sqrt{3^2-4(1)(7)} }{2(1)}[/tex]

    [tex]x=\frac{-3+/-\sqrt{9-28} }{2}[/tex]

    [tex]x=\frac{-3+/-\sqrt{-19} }{2}[/tex]

    your answer is a
