9z+5 X 5z

---- -----

15 81z(exponent 2) -25

**Reiny**, Tuesday, November 25, 2008 at 10:23pmtry typing it like this:

(9z+5)/15 * 5z/(81z^2 - 25)

= (9z+5)/15 * 5z/[9z+5)(9z-5)]

= 1/3 * z/(9z-5) I canceled (9z+5) and a 5

= z/[3(9z-5), z not equal to zero or 5/9

check my steps, sometimes I make error when I am solving and typing at the same time.
