expand (x+1)*(x^2+x+1)

expand

(x + 1) \cdot (x^{2} + x + 1)

x^{3} + 2 x^{2} + 2 x + 1

Solution steps

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

Distribute parentheses

= x x^{2} + xx + x \cdot 1 + 1 \cdot x^{2} + 1 \cdot x + 1 \cdot 1

Simplify

x x^{2} + xx + x \cdot 1 + 1 \cdot x^{2} + 1 \cdot x + 1 \cdot 1 : x^{3} + 2 x^{2} + 2 x + 1

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

(x + h) (x + h)

\frac{57}{4}

(2 x + m)^{2}

e^{0.08}

2 (x^{2} - 9)
