expand (7u(4u-1)(3u-1))/(4u+5)

expand

\frac{7 u ( 4 u - 1 ) ( 3 u - 1 )}{4 u + 5}

\frac{84 u ^{3} - 49 u ^{2} + 7 u}{4 u + 5}

Solution steps

\frac{7 u ( 4 u - 1 ) ( 3 u - 1 )}{4 u + 5}

Expand

7 u (4 u - 1) (3 u - 1) : 84 u^{3} - 49 u^{2} + 7 u

= \frac{84 u ^{3} - 49 u ^{2} + 7 u}{4 u + 5}

- (\frac{x + 1}{( 9 x - 2 ) ( x - 1 )})

(y e^{yz} + \frac{1}{z}) (2)

e^{(2 t)} (sin (2 t) - 1)

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

\frac{9}{4} (4 x + \frac{3}{4})
