<PRE><B>Question 458419</B>
Factor the expression 
25u^2-20uv+4v^2 
This is what I tried by using 3 Term Regular Factoring:
a*c= 25*4
b= 20
My two numbers are -10 and -10 
25u^2-20uv+4v^2
25u^2- -10uv - 10uv + 4v^2
---
Factoring the 1st 2 and the last 2 terms separately you get:
5u(5u-2v)-2v(5u-2v)
--------
Factoring again you get:
= (5u-2v)(5u-2v)
