Factor:

16g^2-26gh-35h^2

The factored form would be (8g + 7h) (2g - 5h)

Step-by-step explanation:

In order to find this, we need to use factors of 16g^2 in the front of the parenthesis. We also need to use factors of - 35h^2 in the second side. Now we try these in the parenthesis and FOIL until we get an appropriate middle term.
