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

expand

(x - 2) (x + 1) (x + 3)

x^{3} + 2 x^{2} - 5 x - 6

Solution steps

(x - 2) (x + 1) (x + 3)

Expand

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

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

Distribute parentheses

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

Simplify

x^{2} x + x^{2} \cdot 3 - xx - x \cdot 3 - 2 x - 2 \cdot 3 : x^{3} + 2 x^{2} - 5 x - 6

= x^{3} + 2 x^{2} - 5 x - 6

\frac{q + 2}{4 - q} + \frac{1}{q + 4} + \frac{1}{q ^{2} - 16}

\frac{1}{2} \times \frac{4}{5}

(3 m + 2 n)^{2}

\frac{12}{3 + 5}

\frac{5}{3} + \frac{1}{6}
