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

expand

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

4 x^{3} + 12 x^{2} - x - 15

Solution steps

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

Distribute parentheses

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

Simplify

2 x \cdot 2 x^{2} + 2 xx + 2 x (- 3) + 5 \cdot 2 x^{2} + 5 x + 5 (- 3) : 4 x^{3} + 12 x^{2} - x - 15

= 4 x^{3} + 12 x^{2} - x - 15
