expand (2x-7)(2x^2+2x-1)

expand

(2 x - 7) (2 x^{2} + 2 x - 1)

4 x^{3} - 10 x^{2} - 16 x + 7

Solution steps

(2 x - 7) (2 x^{2} + 2 x - 1)

Distribute parentheses

= 2 x \cdot 2 x^{2} + 2 x \cdot 2 x + 2 x (- 1) - 7 \cdot 2 x^{2} - 7 \cdot 2 x - 7 (- 1)

Simplify

2 x \cdot 2 x^{2} + 2 x \cdot 2 x + 2 x (- 1) - 7 \cdot 2 x^{2} - 7 \cdot 2 x - 7 (- 1) : 4 x^{3} - 10 x^{2} - 16 x + 7

= 4 x^{3} - 10 x^{2} - 16 x + 7
