Question 1185162

(11z-3)(4z^2-3z-4)

How do I expand the expression combining like terms and simplifying it?
<pre>Best to do distribution of 11x - 3 to the trinomial, VERTICALLY, as follows:
(11z - 3)(4z<sup>2</sup> - 3z - 4) =  11z(4z<sup>2</sup> - 3z - 4) - 3(4z<sup>2</sup> - 3z - 4)      
(11z - 3)(4z<sup>2</sup> - 3z - 4) =  44z<sup>3</sup>    -  33z<sup>2</sup>   -   44z
                          <u>         -  12z<sup>2</sup>   +    9z    +   12</u>
(11z - 3)(4z<sup>2</sup> - 3z - 4) =<b><font color = red><font size = 5> 44z<sup>3</sup> - 45z<sup>2</sup> - 35z  +  12</font></font></b></pre>
