expand

(x + 1) (3 x^{2} - 10 x + 8)

3 x^{3} - 7 x^{2} - 2 x + 8

Solution steps

(x + 1) (3 x^{2} - 10 x + 8)

Distribute parentheses

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

Simplify

x \cdot 3 x^{2} + x (- 10 x) + x \cdot 8 + 1 \cdot 3 x^{2} + 1 \cdot (- 10 x) + 1 \cdot 8 : 3 x^{3} - 7 x^{2} - 2 x + 8

= 3 x^{3} - 7 x^{2} - 2 x + 8

x (2 x - 5)

(7 x + 2)^{2}

- 5 4 x^{2}

\frac{20}{45}

- 4 p + (- 2) + 2 p + 3
