expand (x-1)(x^2-x-1)

expand

(x - 1) (x^{2} - x - 1)

x^{3} - 2 x^{2} + 1

Solution steps

(x - 1) (x^{2} - x - 1)

Distribute parentheses

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

Simplify

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

= x^{3} - 2 x^{2} + 1

\frac{1}{3} \times 60

20 x^{2} - 34 x + 6

4 x^{2} - 2 x + 4

(- 6 + i)^{2}
