expand (-2a^2-4a-2+b)/((a-1)(-4-2a))

expand

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

\frac{- 2 a ^{2} - 4 a - 2 + b}{- 2 a ^{2} - 2 a + 4}

Solution steps

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

Expand

(a - 1) (- 4 - 2 a) : - 2 a^{2} - 2 a + 4

= \frac{- 2 a ^{2} - 4 a - 2 + b}{- 2 a ^{2} - 2 a + 4}

\frac{3 x ^{2} + 9 x - 5}{12}

\frac{( 3 + x ) ^{2} - 3 y ( 2 x - 3 ) - 18 y ^{2}}{2 x ^{2}}

24 e^{- 30 t} + 30 (\frac{4}{5} - \frac{4}{5} e^{- 30 t})

\frac{x ^{3}}{2 ( x + 1 ) ^{2}}
