Could you please help me out with this problem??
Multiply and simplify
z^2-z-12 16z^3-9z
-------- X --------
4z^3-3z^2 4z-16

-----------------------------------
(z-4)(z+3) z(4z-3)(4z+3)
-------- X --------
z^2(4z-3) 4(z-4)

-------------------------------------
[(z+3)z(4z+3)] / [z^2*4]
-------------------------------------
[z(z+3)(4z+3)]/[4z^2]
