expand (k+1)(k+2)(k+3)

expand

(k + 1) (k + 2) (k + 3)

k^{3} + 6 k^{2} + 11 k + 6

Solution steps

(k + 1) (k + 2) (k + 3)

Expand

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

= (k^{2} + 3 k + 2) (k + 3)

Distribute parentheses

= k^{2} k + k^{2} \cdot 3 + 3 kk + 3 k \cdot 3 + 2 k + 2 \cdot 3

Simplify

k^{2} k + k^{2} \cdot 3 + 3 kk + 3 k \cdot 3 + 2 k + 2 \cdot 3 : k^{3} + 6 k^{2} + 11 k + 6

= k^{3} + 6 k^{2} + 11 k + 6

\frac{5 x ^{2}}{x}

14 x^{3} + 18 x^{4}

(4 y)^{3}

e^{5 l n (x)}

(6 - x)^{3}
