    Since this is simple integer factors. For a quadratic of the form ax^2+bx+c, there will be two values, j and k, which satisfy to conditions:

    jk=ac=-18 and j+k=b=3, so j and k must be 6 and - 3

    So factored this is: (x+6) (x-3)

    X^2 + 3x - 18

    2 numbers that multiplied give you - 18

    Those same 2 numbers have to add up to 3

    6 x - 3 = - 18

    6 + - 3 = 3

    (X + 6) (x - 3)
