expand (2+3x+x^2)*(2+x)

expand

(2 + 3 x + x^{2}) \cdot (2 + x)

4 + 8 x + 5 x^{2} + x^{3}

Solution steps

(2 + 3 x + x^{2}) (2 + x)

Distribute parentheses

= 2 \cdot 2 + 2 x + 3 x \cdot 2 + 3 xx + x^{2} \cdot 2 + x^{2} x

Simplify

2 \cdot 2 + 2 x + 3 x \cdot 2 + 3 xx + x^{2} \cdot 2 + x^{2} x : 4 + 8 x + 5 x^{2} + x^{3}

= 4 + 8 x + 5 x^{2} + x^{3}

4 b + 6 - 4

1 + 3.322 \cdot lo g_{10} (20)

2 (g + 8)

(x^{2} - y^{3})^{3}

a^{4} \cdot (- b)
