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

expand

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

x^{3} - 2 x + 1

Solution steps

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

Distribute parentheses

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

Simplify

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

= x^{3} - 2 x + 1

\frac{x ^{3}}{4 x - 8} - \frac{4}{x ^{2} + 2 x}

\frac{3}{7} + \frac{7}{8} + \frac{27}{28}

\frac{5 + i}{6 + 5 i}

\frac{16}{225}

4 n - 1 - 6 n + 8 - 8 n + 15
