expand (3x-1)(2x^2-7x-4)

expand

(3 x - 1) (2 x^{2} - 7 x - 4)

6 x^{3} - 23 x^{2} - 5 x + 4

Solution steps

(3 x - 1) (2 x^{2} - 7 x - 4)

Distribute parentheses

= 3 x \cdot 2 x^{2} + 3 x (- 7 x) + 3 x (- 4) - 1 \cdot 2 x^{2} - 1 \cdot (- 7 x) - 1 \cdot (- 4)

Simplify

3 x \cdot 2 x^{2} + 3 x (- 7 x) + 3 x (- 4) - 1 \cdot 2 x^{2} - 1 \cdot (- 7 x) - 1 \cdot (- 4) : 6 x^{3} - 23 x^{2} - 5 x + 4

= 6 x^{3} - 23 x^{2} - 5 x + 4

(7 + 3 i) - (- 9 + i)

\frac{3 a}{12 b ^{2}} - \frac{a - 4 b}{12 b ^{2}}

(2 x + 4) (x - 1)

(4 x + 5 y)^{2}

- 1 \frac{1}{4}
