expand (x+1)(x^2+x+3)

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

x x^{2} + xx + x \cdot 3 + 1 \cdot x^{2} + 1 \cdot x + 1 \cdot 3 : x^{3} + 2 x^{2} + 4 x + 3

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

34 \cdot 4

\frac{3 7 ^{19}}{3 7 ^{3}}

\frac{x ^{2} - 3 x}{x - 3}

\frac{1}{2} \cdot \frac{6}{7}

(x + 4) (x - 2) (x)
