To divide the two fractions, we multiply the first fraction by the reciprocal of the second fraction:
(z^2 - 4)/(z - 3) * (z^2 + z - 12)/(z + 2)
Factor the expressions:
=((z - 2)(z + 2)/(z - 3)) * ((z + 4)(z - 3)/(z + 2))
Next, cancel out common factors in the numerator and denominator:
=((z - 2)(z + 4))/(z + 2)
So, the quotient in simplest form is (z - 2)(z + 4) / (z + 2).
The restrictions on the variable are z cannot be equal to 3 (due to the denominator of (z - 3)) and z cannot be equal to -2 (due to the denominator of (z + 2)) as these values would result in division by zero.
(z^(2)-4)/(z-3) divided by (z+2)/(z^(2)+z-12)
