Factor 56x2 - 8x - 7x + 1 by grouping.

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
