expand (18z^3+16z^2-21z-4)/((6z-1)(2z^3-1))

expand

\frac{18 z ^{3} + 16 z ^{2} - 21 z - 4}{( 6 z - 1 ) ( 2 z ^{3} - 1 )}

\frac{18 z ^{3} + 16 z ^{2} - 21 z - 4}{12 z ^{4} - 6 z - 2 z ^{3} + 1}

Solution steps

\frac{18 z ^{3} + 16 z ^{2} - 21 z - 4}{( 6 z - 1 ) ( 2 z ^{3} - 1 )}

Expand

(6 z - 1) (2 z^{3} - 1) : 12 z^{4} - 6 z - 2 z^{3} + 1

= \frac{18 z ^{3} + 16 z ^{2} - 21 z - 4}{12 z ^{4} - 6 z - 2 z ^{3} + 1}

- 2 (\frac{2}{35} - s t)

\frac{1}{( x ^{2} + 4 ) ^{2}}

m l e f t (a - b) + (a - b)

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

\frac{1}{( 1 + 4 x ) ^{2}}
