expand (s+1)(s^2+s+1)

expand

(s + 1) (s^{2} + s + 1)

s^{3} + 2 s^{2} + 2 s + 1

Solution steps

(s + 1) (s^{2} + s + 1)

Distribute parentheses

= s s^{2} + ss + s \cdot 1 + 1 \cdot s^{2} + 1 \cdot s + 1 \cdot 1

Simplify

s s^{2} + ss + s \cdot 1 + 1 \cdot s^{2} + 1 \cdot s + 1 \cdot 1 : s^{3} + 2 s^{2} + 2 s + 1

= s^{3} + 2 s^{2} + 2 s + 1

\frac{3}{4} + \frac{2}{8}

\frac{5 x ^{7} y ^{2}}{25 x y ^{6}}

x^{2} \cdot (- 1)

- 10 + 510
