    Do you know how to factor trinomials into two binomial factors? That's the key to this problem.

    6x2 + 17x + 7 = (2x + ?)(3x + ?)

    2x2 + 7x + 3 = (2x + ?)(x + ?)

    Fill in the question marks.

    6x2 + 17x + 7 = (2x + ?)(3x + ?)

    2x2 + 7x + 3 = (2x + ?)(x + ?)



    (2x + 1) (3x+7)

    (2x +1)(x + 3)

    ok nice thanks alot
