need to show your work first
factor out a (z+3) in the numerator and denominator, leaving 8/9
cancel z^2 and leave z^7 in denominator
simplify everything to factors to see what you can cross out
get rid of 2 z's top and bottom; and the (z+3) top and bottom to get; and the 8's top to bottom to get:
ack!!... 1/9z^7 :) forgot how to subtract
does that make sense?
i think so will u show the work so i can make notes for the next problem
i did show the work.... cant really see how to show any more of it :/
in my work i think i forgot about the 9
when everything is factored; you simple cancel out (its a bad term really) everything that is the same top to bottom; because they go to 1
z/z = 1
8/8 = 1
(z+3)/(z+3) = 1
so they become redundant in the equation
