<PRE><B>Question 319278</B>
1) Find the greatest common factor of the two expression: Simplify
20uy^8z^6 and 28u^7y^4
---
gcf for 20 and 28 is 4
gcf for u and u^7 is u
gcf for y^8 and y^4 is y^4
gcf for z^6 and no z is no z
---------------------------------
GCF = 4uy^4
========================================================================
2) Find the least common multiple of the two expressions: Simplify
3t^6x^8y^5 and 12x^3y^6
lcm of 3 and 12 is 12
lcm of t^6 and no t is t^6
lcm of x^8 and x^3 is x^8
lcm of y^5 and y^6 is y^6
---
LCM = 12t^6*x^8*y^6
======================================================== 
3) Factor Completely: 27z^3+125
No common factor
------------------------------- 
4) Factor: 9t+wt+9y+yw
---
t(9+w) + y(9+w)
---
= (9+w)(t+y)
-------------------------------
 
5) Factor: -8t+xt-24x+3x^2
---
= -(8t -xt + 24x - 3x^2)
---
= -(t(8-x) + 3x(8-x))
---
= -(8-x)(t+3x)
