SAT Mathematics Practice Test 2

Dividing $5\mathit{x}-2$ by $\mathit{x}+3$ gives:
$\mathit{x}+3)5\mathit{x}-2$
Therefore ,the expression $\frac{5\mathit{x}-2}{\mathit{x}+3}$ can be written as $5-\frac{17}{\mathit{x}+3}$
Alternatively,$\frac{5\mathit{x}-2}{\mathit{x}+3}$ can be written as

Choices A and B are incorrect and may result from incorrectly canceling out the x in the expression $\frac{5\mathit{x}-2}{\mathit{x}+3}$ Choice C is incorrect and may result fromfinding an incorrect remainder when performing long division.
