Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Factor each expression:
------------------------------
Find the LCM for
14z^2+56z = 2*7z(z+4)
------------------
7z^2+49z+84 = 7(z^2+7z+12) = 7(z+3)(z+4)
---------------------
The LCM must contain all the factors of the
2 expressions in their highest power:
---
LCM = 2*7*z(z+3)(z+4)
