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

expand

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

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

Solution steps

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

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

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

\frac{1}{( 3 x ^{2} + 5 x ) ^{3}}

10 (2 - 2)

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

- x (ln (x) + y^{2} \cdot ln (y)) d y

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