Question 442222: add, simplify if possible; 2z/z^2-64 + z/z-8
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! add, simplify if possible;
2z/(z^2-64) + z/(z-8)
-------
lcd = z^2-64
----
Rewrite each fraction with the lcd as its denominator:
(2z)/lcd + (z(z+8))/lcd
-----------------------------
[2z+z^2+8z)/lcd
--------------------------
Final = (z^2 + 10z)/(z^2-64)
