    Step-by-step explanation:

    (8x-1) (7x-1) The question leaves you with the partially factored equation: 8x (7x-1) - 1 (7x-1) Now if you look at the partially factored equation, you'll see that both terms have (7x-1) as one of their factors. So let's take that (7x-1) as a factor and divide both terms by (7x-1), giving us (8x (7x-1) - 1 (7x-1)) / (7x-1) The (7x-1) factors cancel out, leaving us with (8x - 1) So our 2 factors are (7x-1) and (8x-1). Looking at the available options, the only correct one is (8x-1) (7x-1)

    - 8x (7x - 1) (7x - 1)

    Step-by-step explanation:

    so the first thing you would do is break it apart as if it is two different problems.

    56x2 - 8x

    - 7x + 1

    then you would take out the greatest common multiple

    8x (7x - 1)

    - (7x - 1)

    then you would put them together

    - 8x (7x - 1) (7x - 1)

    or you could just leave it as

    - 8x (7x - 1) ^2
