expand (x-1)(3x^2-8x+2)

expand

(x - 1) (3 x^{2} - 8 x + 2)

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

Solution steps

(x - 1) (3 x^{2} - 8 x + 2)

Distribute parentheses

= x \cdot 3 x^{2} + x (- 8 x) + x \cdot 2 - 1 \cdot 3 x^{2} - 1 \cdot (- 8 x) - 1 \cdot 2

Simplify

x \cdot 3 x^{2} + x (- 8 x) + x \cdot 2 - 1 \cdot 3 x^{2} - 1 \cdot (- 8 x) - 1 \cdot 2 : 3 x^{3} - 11 x^{2} + 10 x - 2

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

2 \times 9

125 \frac{2}{3}

(5 a - 3 b)^{2}

(0.9)^{2}

\frac{\frac{x ^{2} + 11 x + 30}{x ^{2} - 9}}{\frac{x ^{2} - 36}{x - 3}}
