Note: CAS stands for "Computer Algebra System"
The fact that [tex]x - \frac{41}{x+4} + 8[/tex] is the result that the CAS produces indicates we're pretty much at the answer. All we have to do is rearrange terms to go from [tex]x - \frac{41}{x+4} + 8[/tex] to [tex]x+8 - \frac{41}{x+4}[/tex]
The "x+8" portion is the quotient while the remaining stuff is the remainder (specifically -41 is the remainder)
So the answer is choice A) -41
