expand (3x-4)(5-2x)(4x+1)

expand

(3 x - 4) (5 - 2 x) (4 x + 1)

- 24 x^{3} + 86 x^{2} - 57 x - 20

Solution steps

(3 x - 4) (5 - 2 x) (4 x + 1)

Expand

(3 x - 4) (5 - 2 x) (4 x + 1) : (- 6 x^{2} + 23 x - 20) (4 x + 1)

= (- 6 x^{2} + 23 x - 20) (4 x + 1)

Distribute parentheses

= - 6 x^{2} \cdot 4 x - 6 x^{2} \cdot 1 + 23 x \cdot 4 x + 23 x \cdot 1 - 20 \cdot 4 x - 20 \cdot 1

Simplify

- 6 x^{2} \cdot 4 x - 6 x^{2} \cdot 1 + 23 x \cdot 4 x + 23 x \cdot 1 - 20 \cdot 4 x - 20 \cdot 1 : - 24 x^{3} + 86 x^{2} - 57 x - 20

= - 24 x^{3} + 86 x^{2} - 57 x - 20

(- 5 x^{2} + 6 x + 7) + (- x^{2} + 4 x)

(- 12 + 10 i) + (4 - 8 i)
