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

expand

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

6 x^{3} - 13 x^{2} - 13 x + 20

Solution steps

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

Distribute parentheses

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

Simplify

3 x^{2} \cdot 2 x + 3 x^{2} (- 5) + x \cdot 2 x + x (- 5) - 4 \cdot 2 x - 4 (- 5) : 6 x^{3} - 13 x^{2} - 13 x + 20

= 6 x^{3} - 13 x^{2} - 13 x + 20

\frac{7 x - 14}{x - 2}

\frac{4}{9 x ^{2} - 45 x} - \frac{6 x}{x ^{2} - 25}

3 6^{0.5}

a (a - x) + 3 a (x + 2 a) - a (x - 3 a)

(\frac{x ^{\frac{1}{2}}}{2} - \frac{1}{2 x})^{2}
