expand (2x-5)(3x^2-4x-8)

expand

(2 x - 5) (3 x^{2} - 4 x - 8)

6 x^{3} - 23 x^{2} + 4 x + 40

Solution steps

(2 x - 5) (3 x^{2} - 4 x - 8)

Distribute parentheses

= 2 x \cdot 3 x^{2} + 2 x (- 4 x) + 2 x (- 8) - 5 \cdot 3 x^{2} - 5 (- 4 x) - 5 (- 8)

Simplify

2 x \cdot 3 x^{2} + 2 x (- 4 x) + 2 x (- 8) - 5 \cdot 3 x^{2} - 5 (- 4 x) - 5 (- 8) : 6 x^{3} - 23 x^{2} + 4 x + 40

= 6 x^{3} - 23 x^{2} + 4 x + 40

\frac{121}{4}

\frac{x ^{\frac{1}{2}} y ^{\frac{2}{3}}}{x ^{\frac{1}{4}} y ^{\frac{1}{6}}}

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

\frac{1}{5 + 2}

i + (1 - i)^{4}
