  1. Here we see that the x² term has a coefficient of 2, so the factorized form will be (x±?)(2x±?).
    From the constant term of -3, we know that the factorized expression can only be (?x±1)(?x±3).
    A couple of tries will give the correct answer, noting that the middle term is -5x:
    2x²-5x-3
    =(2x+1)(x-3)
