<PRE><B>Question 319026</B>
1) Factor: x^2-9y^2
= (x-3y)(x+3y)
-------------------------------------- 
2) Factor the quadratic expression: u^2+10u+25
= (u+5)^2
--------------------------------------- 
3) Factor completely, The sum of two or difference of two cubes: 64+27z^3
= (4+3z)(16-4*3z+9z^^2)
---
= (4+3z)(16-12z+9z^2
------------------------------ 
4) Factor Completely: 16x^3-x^3-z^4
15x^3-z^4
Cannot be factored further.
