7x^2+26x-8 factor the trinomial or state if it's prime. Using the FOIL method
---------
7x^2+26x-8
---
Factoring is to some extent trial and error.
For this one, obviously, it's (x + a)*(7x + b).
The product of a*b = -8, so the signs are different, one + and one minus.
----
a & b are:
1 & 8 or 2 & 4.
Find the combination that works.

You gain nothing by having someone do it for you.
