expand-(4x^2+2x)/((2x-1)^3)

expand

- \frac{4 x ^{2} + 2 x}{( 2 x - 1 ) ^{3}}

- \frac{4 x ^{2} + 2 x}{8 x ^{3} - 12 x ^{2} + 6 x - 1}

Solution steps

- \frac{4 x ^{2} + 2 x}{( 2 x - 1 ) ^{3}}

(2 x - 1)^{3} = 8 x^{3} - 12 x^{2} + 6 x - 1

= - \frac{4 x ^{2} + 2 x}{8 x ^{3} - 12 x ^{2} + 6 x - 1}

h^{\frac{1}{3}} + (h + 1)^{\frac{1}{3}} (h^{\frac{1}{3}} - (h + 1)^{\frac{1}{3}})

- 2 (e^{x} x - e^{x})

\frac{x ^{2} - 6 x + 12}{( x - 2 ) ( x - 1 ) ^{2}}

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