expand (x+3)/((x^2+9)^2)

expand

\frac{x + 3}{( x ^{2} + 9 ) ^{2}}

\frac{x + 3}{x ^{4} + 18 x ^{2} + 81}

Solution steps

\frac{x + 3}{( x ^{2} + 9 ) ^{2}}

(x^{2} + 9)^{2} = x^{4} + 18 x^{2} + 81

= \frac{x + 3}{x ^{4} + 18 x ^{2} + 81}

(1 + i, 2 - 3 i) y (2 - i, - 1 + 2 i)

\frac{16 ( x - 4 )}{x - 16}

\frac{( x - 5 ) ( x + 2 )}{( x - 1 ) ( x - 8 )}

(x + π)^{2}
