factor (k(k+1)+2(k+1))/2

factor

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

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

Solution steps

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

Expand

k (k + 1) + 2 (k + 1) : k^{2} + 3 k + 2

= \frac{k ^{2} + 3 k + 2}{2}

Factor

k^{2} + 3 k + 2 : (k + 1) (k + 2)

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

3 sin^{2} (x) + 5 sin (x) - 2
