expand (n(5n+7))/((n+1)^2)

expand

\frac{n ( 5 n + 7 )}{( n + 1 ) ^{2}}

\frac{5 n ^{2} + 7 n}{n ^{2} + 2 n + 1}

Solution steps

\frac{n ( 5 n + 7 )}{( n + 1 ) ^{2}}

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

= \frac{n ( 5 n + 7 )}{n ^{2} + 2 n + 1}

Expand

n (5 n + 7) : 5 n^{2} + 7 n

= \frac{5 n ^{2} + 7 n}{n ^{2} + 2 n + 1}

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

\frac{d}{d y} ((x) (\frac{x ^{2}}{c ^{2}} - \frac{y ^{9}}{d ^{2}}))

\frac{3336.24}{0.89} - \frac{0.66 x}{0.89}

e^{3 (l n (x) + c)}

\frac{c - 1}{( c + 3 ) ( c - 4 )}
