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

expand

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

2 x^{3} - 7 x^{2} + 7 x - 5

Solution steps

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

Distribute parentheses

= x^{2} \cdot 2 x + x^{2} (- 5) - x \cdot 2 x - x (- 5) + 1 \cdot 2 x + 1 \cdot (- 5)

Simplify

x^{2} \cdot 2 x + x^{2} (- 5) - x \cdot 2 x - x (- 5) + 1 \cdot 2 x + 1 \cdot (- 5) : 2 x^{3} - 7 x^{2} + 7 x - 5

= 2 x^{3} - 7 x^{2} + 7 x - 5

\frac{75}{20}

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

i^{4} + i^{- 12}
