expand (x-5)(x+1)(x+2)

expand

(x - 5) (x + 1) (x + 2)

x^{3} - 2 x^{2} - 13 x - 10

Solution steps

(x - 5) (x + 1) (x + 2)

Expand

(x - 5) (x + 1) (x + 2) : (x^{2} - 4 x - 5) (x + 2)

= (x^{2} - 4 x - 5) (x + 2)

Distribute parentheses

= x^{2} x + x^{2} \cdot 2 - 4 xx - 4 x \cdot 2 - 5 x - 5 \cdot 2

Simplify

x^{2} x + x^{2} \cdot 2 - 4 xx - 4 x \cdot 2 - 5 x - 5 \cdot 2 : x^{3} - 2 x^{2} - 13 x - 10

= x^{3} - 2 x^{2} - 13 x - 10
