2bc + 4b - 5c - 10
----
This is the form you create when you apply FOIL to
determine the product of two binomials.
-----
You need to un-FOIL the form as follows:
-----
Factor the 1st 2 and the last 2 terms separately:
2b(c+2) - 5(c+2)
----
Factor again to get the answer:
---
(c+2)(2b-5)

2bc+%2B+4b+-+5c+-+10......group first two and second two terms
=%282bc+%2B+4b%29+-+%285c+%2B10%29
=2b%28c+%2B+2%29+-+5%28c+%2B2%29
=%282b+-+5%29%28c+%2B2%29
