expand (1-nx^2)/((1+nx^2)^2)

expand

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

\frac{1 - n x ^{2}}{1 + 2 n x ^{2} + n ^{2} x ^{4}}

Solution steps

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

(1 + n x^{2})^{2} = 1 + 2 n x^{2} + n^{2} x^{4}

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

- lo g_{10} (2) (6 - x)

\frac{8 s ^{2} + 18}{( s ^{2} + 4 s + 6 ) ^{2}}
