    15x^2 + 28x + 5 = 0

    (5x + 1)(3x + 5) = 0

    5x + 1 = 0

    5x = -1

    x = -1/5

    3x + 5 = 0

    3x = -5

    x = -5/3

    Oh, you can handle this one... give it a shot.

    Here's a hint: the only factors of 15 are 1, 3, 5, 15. The only factors of 5 are 1 and 5. Even if your instincts aren't good, there aren't that many combinations to check.

    The answer is (3x+5) (5x+1)

    If you need explanation, I don't mind giving you a step by step way of tacking this or any question on math.

    when you factor it you get (3x+5)(5x+1) because it has to multiply to 5 and add to 28
