    X^2 - x - 6

    Let's factorise. So we pick two numbers such that their product gives (-6) and

    adding them up gives us (-1)

    Our choice pick is - 3 and 2

    So we have: X^2 - 3x + 2x - 6 = 0

    Factorimg we have X (X - 3) + 2 (X - 3) = 0

    So (X - 3) and (X + 2) are the solution to the equation.

    Hence my answer is X - 3 and X + 2. None of the option applies.
