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

expand

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

\frac{4 x}{9 x ^{4} - 6 x ^{2} + 1}

Solution steps

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

(3 x^{2} - 1)^{2} = 9 x^{4} - 6 x^{2} + 1

= \frac{4 x}{9 x ^{4} - 6 x ^{2} + 1}

\frac{( 2 a ^{2} b ^{4} - a ^{4} b ) ^{3}}{8}

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

(5 b, 3, - c) (6, a, 2)

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

5^{2} - 14 \cdot 5 + 54
