<PRE><B>Question 221647</B>
factor W^2+10w+16 
---------
The capital W and the small w have no particular meaning.
----------------------
To factor, think of two numbers whose product is 16 and whose sum is 10.
---
The numbers are 8 and 2.
So replace 10w by 8w + 2w to get:
w^2 + 8w + 2w + 16
---
Factor the 1st two and the last two terms separately to get:
w(w+8) +2(w+8)
---
Factor again to get the final answer:
(w+8)(w+2)
------------------
This procedure is called the AC Method.
