expand (2a)/((a^2-b^2)(a^2+3b^2))

expand

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

\frac{2 a}{a ^{4} + 2 a ^{2} b ^{2} - 3 b ^{4}}

Solution steps

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

Expand

(a^{2} - b^{2}) (a^{2} + 3 b^{2}) : a^{4} + 2 a^{2} b^{2} - 3 b^{4}

= \frac{2 a}{a ^{4} + 2 a ^{2} b ^{2} - 3 b ^{4}}

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

- \frac{( r _{2} w ^{2} L c - r _{1} ) ( 1 - w ^{2} L c )}{w ^{2} c ^{3}}

\frac{3 s ^{3} + 2 s ^{2} + 4 s - 1}{( s ^{2} + 4 ) ( s ^{2} + 9 )}

(- x cos^{2} (y) - x sin^{2} (y))^{2}

(3 - cos (t)) \cdot (sin (t))
