Answer
$\dfrac{5x+8}{x}; x \ne0$
Work Step by Step
Factor the numerator and the denominator completely to obtain:
$=\dfrac{3x(5x+8)}{3x(x)}$
Cancel the common factors to obtain:
$\require{cancel}
\\=\dfrac{\cancel{3x}(5x+8)}{\cancel{3x}(x)}
\\=\dfrac{5x+8}{x}; x \ne0$
($x$ cannot be $0$ because it will make the original expression undefined.)
