simplify (4a-1)/(b-2a)-(2a)/(4b-8a)

simplify

\frac{4 a - 1}{b - 2 a} - \frac{2 a}{4 b - 8 a}

\frac{7 a - 2}{2 ( b - 2 a )}

Solution steps

\frac{4 a - 1}{b - 2 a} - \frac{2 a}{4 b - 8 a}

Cancel

\frac{2 a}{4 b - 8 a} : \frac{a}{2 ( b - 2 a )}

= \frac{4 a - 1}{b - 2 a} - \frac{a}{2 ( b - 2 a )}

Simplify

\frac{4 a - 1}{b - 2 a} - \frac{a}{2 ( b - 2 a )} : \frac{( 4 a - 1 ) \cdot 2 - a}{2 ( b - 2 a )}

= \frac{( 4 a - 1 ) \cdot 2 - a}{2 ( b - 2 a )}

Simplify

(4 a - 1) \cdot 2 - a : 7 a - 2

= \frac{7 a - 2}{2 ( b - 2 a )}

\frac{x ^{2} - 1}{x ^{2} - 5 x - 6}

\frac{1}{x ^{- 4}}
