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

expand

(3 x + 5) (2 x^{2} - 2 x - 1)

6 x^{3} + 4 x^{2} - 13 x - 5

Solution steps

(3 x + 5) (2 x^{2} - 2 x - 1)

Distribute parentheses

= 3 x \cdot 2 x^{2} + 3 x (- 2 x) + 3 x (- 1) + 5 \cdot 2 x^{2} + 5 (- 2 x) + 5 (- 1)

Simplify

3 x \cdot 2 x^{2} + 3 x (- 2 x) + 3 x (- 1) + 5 \cdot 2 x^{2} + 5 (- 2 x) + 5 (- 1) : 6 x^{3} + 4 x^{2} - 13 x - 5

= 6 x^{3} + 4 x^{2} - 13 x - 5

(a - b)^{5}

2 x (x - 1)

(x^{2} - 4) (x^{2} + 6 x + 9)

\frac{x ^{2} - 8}{x ^{2} - 10 x + 21} + \frac{5 - 2 x}{x ^{2} - 10 x + 21}

\frac{30}{7}
