<PRE><B>Question 205829</B>
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]

=====================================
