expand (2x-1)(x^2-10x+8)

expand

(2 x - 1) (x^{2} - 10 x + 8)

2 x^{3} - 21 x^{2} + 26 x - 8

Solution steps

(2 x - 1) (x^{2} - 10 x + 8)

Distribute parentheses

= 2 x x^{2} + 2 x (- 10 x) + 2 x \cdot 8 - 1 \cdot x^{2} - 1 \cdot (- 10 x) - 1 \cdot 8

Simplify

2 x x^{2} + 2 x (- 10 x) + 2 x \cdot 8 - 1 \cdot x^{2} - 1 \cdot (- 10 x) - 1 \cdot 8 : 2 x^{3} - 21 x^{2} + 26 x - 8

= 2 x^{3} - 21 x^{2} + 26 x - 8

\frac{2 + 14 i}{9 + 14 i}
