expand (8r+18)/((r+3)(9r-28))

expand

\frac{8 r + 18}{( r + 3 ) ( 9 r - 28 )}

\frac{8 r + 18}{9 r ^{2} - r - 84}

Solution steps

\frac{8 r + 18}{( r + 3 ) ( 9 r - 28 )}

Expand

(r + 3) (9 r - 28) : 9 r^{2} - r - 84

= \frac{8 r + 18}{9 r ^{2} - r - 84}

- 30 x + 780 (1 - e^{- \frac{x}{3}})

t^{\frac{7}{2}} (t^{2} - 4 t + 23)

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

x e^{x} (x + 2)
