factor: 128x^2 - 348x - 11
-----------------
It'll be (ax + 1)*(bx - 11), where a*b = 128
The signs are different because the product is negative.
It's -11, because the -384 is a large number.
-----
Find a pair of factors of 128 that work (both positive).
There's no "secret" to factoring, it's trial and error.
You need the practice more than I do.
