expand (3x-10)(x^2+2x-1)

expand

(3 x - 10) (x^{2} + 2 x - 1)

3 x^{3} - 4 x^{2} - 23 x + 10

Solution steps

(3 x - 10) (x^{2} + 2 x - 1)

Distribute parentheses

= 3 x x^{2} + 3 x \cdot 2 x + 3 x (- 1) - 10 x^{2} - 10 \cdot 2 x - 10 (- 1)

Simplify

3 x x^{2} + 3 x \cdot 2 x + 3 x (- 1) - 10 x^{2} - 10 \cdot 2 x - 10 (- 1) : 3 x^{3} - 4 x^{2} - 23 x + 10

= 3 x^{3} - 4 x^{2} - 23 x + 10

- 8 - 7

\frac{4}{3} \div 2

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

5 x^{2} + 2 x

40 x^{3} - 60 x^{2} - 10 x + 15
