expand (x+1)(2x^2-10x-9)

expand

(x + 1) (2 x^{2} - 10 x - 9)

2 x^{3} - 8 x^{2} - 19 x - 9

Solution steps

(x + 1) (2 x^{2} - 10 x - 9)

Distribute parentheses

= x \cdot 2 x^{2} + x (- 10 x) + x (- 9) + 1 \cdot 2 x^{2} + 1 \cdot (- 10 x) + 1 \cdot (- 9)

Simplify

x \cdot 2 x^{2} + x (- 10 x) + x (- 9) + 1 \cdot 2 x^{2} + 1 \cdot (- 10 x) + 1 \cdot (- 9) : 2 x^{3} - 8 x^{2} - 19 x - 9

= 2 x^{3} - 8 x^{2} - 19 x - 9
