Answer
$x^{2} + 7x + 18 + \frac{42}{x-3}$
Work Step by Step
$ \hspace{11.5mm}x^{2} + 7x + 18$
$ x - 3\overline{)x^{3} + 4x^{2} - 3x - 12}$
$ \hspace{11mm}\underline{x^{3} + 3x^{2}}$
$ \hspace{21mm}7x^{2} - 3x$
$ \hspace{21mm}\underline{7x^{2} - 21x}$
$\hspace{33mm}18x - 12$
$ \hspace{33mm}\underline{18x - 54}$
$ \hspace{45mm}42$
