expand (x+1)(x-3)(x+6)

expand

(x + 1) (x - 3) (x + 6)

x^{3} + 4 x^{2} - 15 x - 18

Solution steps

(x + 1) (x - 3) (x + 6)

Expand

(x + 1) (x - 3) (x + 6) : (x^{2} - 2 x - 3) (x + 6)

= (x^{2} - 2 x - 3) (x + 6)

Distribute parentheses

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

Simplify

x^{2} x + x^{2} \cdot 6 - 2 xx - 2 x \cdot 6 - 3 x - 3 \cdot 6 : x^{3} + 4 x^{2} - 15 x - 18

= x^{3} + 4 x^{2} - 15 x - 18

9 x^{3} y^{- 5} \cdot 3^{- 2} x^{- 4} y^{5}

- 34.7 + (- 83.5)

\frac{3}{2 1}

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

\frac{4}{5} x + \frac{3}{8} + \frac{3}{10} x
