expand (2(2s-1))/(2s^2-s-2)

expand

\frac{2 ( 2 s - 1 )}{2 s ^{2} - s - 2}

\frac{4 s - 2}{2 s ^{2} - s - 2}

Solution steps

\frac{2 ( 2 s - 1 )}{2 s ^{2} - s - 2}

Expand

2 (2 s - 1) : 4 s - 2

= \frac{4 s - 2}{2 s ^{2} - s - 2}

\frac{6 ( y - 3 )}{43}

\frac{x}{( z - 1 ) ( z - 3 )}

(y^{2} + x y^{3}) d x + (5 y^{2} - x y + y^{3} sin (y) d y)

\frac{s ^{2} - 1}{s ^{2} ( s ^{2} + 2 )}

, (2 + \frac{2}{7}) (1 + \frac{1}{6}) (2 + \frac{2}{3}) \cdot \frac{1}{8}
