Question 1091039
{{{(x^2+64)/(x+4)}}}


{{{((x+4)(x^2-4x+16))/(x+4)}}}


{{{highlight(x^2-4x+16)}}}


-

The setup to start the LONG division would begin this way, with only first step shown:
<pre>
            x^2
       _________________________________________
x+4    |    x^3     0x^2     0x     64
       |    x^3     4x^2
       |-----------------
            0      -4x^2

...not finished...
</pre>
Can you continue that?
