expand (2x-1)(2x^2-5x-3)

expand

(2 x - 1) (2 x^{2} - 5 x - 3)

4 x^{3} - 12 x^{2} - x + 3

Solution steps

(2 x - 1) (2 x^{2} - 5 x - 3)

Distribute parentheses

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

Simplify

2 x \cdot 2 x^{2} + 2 x (- 5 x) + 2 x (- 3) - 1 \cdot 2 x^{2} - 1 \cdot (- 5 x) - 1 \cdot (- 3) : 4 x^{3} - 12 x^{2} - x + 3

= 4 x^{3} - 12 x^{2} - x + 3

(- 7)^{6}

4 x - 3 y + 2 x + y + 7

x \cdot (- 2) x

9 (g - 5 h + 1)

i^{3} + i^{20}
