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

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

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

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