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

expand

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

2 x^{3} - 11 x^{2} + 10 x + 15

Solution steps

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

Distribute parentheses

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

Simplify

x \cdot 2 x^{2} + x (- 5 x) + x (- 5) - 3 \cdot 2 x^{2} - 3 (- 5 x) - 3 (- 5) : 2 x^{3} - 11 x^{2} + 10 x + 15

= 2 x^{3} - 11 x^{2} + 10 x + 15

15 \times 4

m n^{4} (m^{3} - 2 m^{2} n + 4 m n^{2} - n^{2} + 4)

x + 3 + \frac{3 x}{x + 5}

- 9 + - 28

(\frac{1}{e})^{2} - 2 ln (\frac{1}{e})
