expand (x+4)(-3x^2-4x+2)

expand

(x + 4) (- 3 x^{2} - 4 x + 2)

- 3 x^{3} - 16 x^{2} - 14 x + 8

Solution steps

(x + 4) (- 3 x^{2} - 4 x + 2)

Distribute parentheses

= x (- 3 x^{2}) + x (- 4 x) + x \cdot 2 + 4 (- 3 x^{2}) + 4 (- 4 x) + 4 \cdot 2

Simplify

x (- 3 x^{2}) + x (- 4 x) + x \cdot 2 + 4 (- 3 x^{2}) + 4 (- 4 x) + 4 \cdot 2 : - 3 x^{3} - 16 x^{2} - 14 x + 8

= - 3 x^{3} - 16 x^{2} - 14 x + 8
