expand 1/(k(k+1))+(k+1)

expand

\frac{1}{k ( k + 1 )} + (k + 1)

\frac{1}{k ^{2} + k} + k + 1

Solution steps

\frac{1}{k ( k + 1 )} + (k + 1)

Remove parentheses:

(a) = a

= \frac{1}{k ( k + 1 )} + k + 1

Expand

k (k + 1) : k^{2} + k

= \frac{1}{k ^{2} + k} + k + 1

(2 - 4 i)^{7}

(x + 1) ln (3)

(Δ x + x)^{2}

\frac{3 x + 4}{( 6 x ^{2} + 16 x ) ^{3}}

\frac{2 ( 7 - 41 )}{7}
