simplify (\frac{15-3x)/(x+5)}{(5x-x^2)/(5x+1)}

simplify

\frac{\frac{15 - 3 x}{x + 5}}{\frac{5 x - x ^{2}}{5 x + 1}}

\frac{3 ( 5 x + 1 )}{( x + 5 ) x}

Solution steps

\frac{\frac{15 - 3 x}{x + 5}}{\frac{5 x - x ^{2}}{5 x + 1}}

Apply the fraction rule:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

= \frac{( 15 - 3 x ) ( 5 x + 1 )}{( x + 5 ) ( 5 x - x ^{2} )}

Cancel

\frac{( 15 - 3 x ) ( 5 x + 1 )}{( x + 5 ) ( 5 x - x ^{2} )} : \frac{3 ( 5 x + 1 )}{( x + 5 ) x}

= \frac{3 ( 5 x + 1 )}{( x + 5 ) x}

\frac{9 \cdot ( 3 ^{- 2} ) ^{3} \cdot 3 ^{- 3}}{3 ^{- 6} \cdot 3}

\frac{2 lo g _{3} ( 5 )}{lo g _{3} ( 4 )}

32 \cdot 9
