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

expand

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

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

Solution steps

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

Remove parentheses:

(a) = a

= \frac{n ( n + 1 )}{2 ( 2 n + 1 )} + n + 1

\frac{n ( n + 1 )}{2 ( 2 n + 1 )} = \frac{n ^{2} + n}{4 n + 2}

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

(5 + 3 e^{7 t})^{4}

(1 + p - 2) (1 + p + 2)

(y = 2, x + 6) (\frac{x}{2} - y = 3)

- 3 (7 - 14)

- \frac{3 ( 199 + 77 73 )}{8} + 1715 + 25073
