    well if the question is X^2 +3x -7

    then you should get two answers.

    if you use the quadrac formula you get

    -3+(square root of 37)
    2

    and

    -3-(square root of 37)
    2

    I don't understand how you've written it?
    Is it supposed to be:
    ((X*2) + (3*X)) * - 7 = 0

    Or..
    (X² + 3*x) * -7 = 0

    Edit: Wait, or is it:
    (X²+3) * X-7 = 0
