expand (-1-3x)/(2(-2+x))

expand

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

\frac{- 1 - 3 x}{- 4 + 2 x}

Solution steps

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

Expand

2 (- 2 + x) : - 4 + 2 x

= \frac{- 1 - 3 x}{- 4 + 2 x}

(x^{2} + 1 - x^{2} - 1)^{2}

\frac{5 x ^{2} + 20 x + 6}{x ( x + 1 ) ^{2}}

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

(x + 2) (x^{2} - 4)

(3 x^{2} y - 6 x) d x + (x^{3} + 2 y) d y
