You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).

We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:

(2x _ _)(x _ _)

Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.

This gives our final answer as:

(2x - 5)(x + 7)

We cannot use foil on this expression as there are no brackets to expand.

I hope this helps!
