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

expand

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

12 x^{3} - 26 x^{2} + x + 15

Solution steps

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

Distribute parentheses

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

Simplify

3 x \cdot 4 x^{2} + 3 x (- 2 x) + 3 x (- 3) - 5 \cdot 4 x^{2} - 5 (- 2 x) - 5 (- 3) : 12 x^{3} - 26 x^{2} + x + 15

= 12 x^{3} - 26 x^{2} + x + 15

\frac{2}{3} + \frac{5}{7}

(4 a^{2} b - 3 a b^{2} + 2 ab + 5) + (2 a^{2} b + 3 a b^{2} - 7 ab)

(3 x - 2 y) (3 x + 2 y)

(5 x - 4 y) (5 x + 4 y)

x (- x)
