Question 706027: What is the quotient in simplest form? State any restrictions on the variable.

(z^2-4/z-3) / (z+3/z^2+z-12)
---------
[(z-2)(z+2)/(z-3)] / [(z+3)/((x+4)(x-3))]
---------
Invert the denominator and multiply:
------
[(z-2)(z+2)/(z-3)] * [((z+4)(z-3)/(z+3))]
-----
Cancel (z-3) factors to get:
------
[(z-2)(z+2)/1] * [((z+4)/(z+3))]
------
= [(z-2)(z+2)(z+4)/(z+3)
-----
Restrictions:
z cannot be 3, -3
