$= - 12 x^{4} + 4 x^{3} - 4 x^{2}$ $=color(blue)(-12x^4 +4x^3-4x^2$

Explanation:

$(- 4 x^{2}) (3 x^{2} - x + 1)$ $color(blue)((−4x^2))(3x^2−x+1)$

$= (- 4 x^{2}) (3 x^{2}) + (- 4 x^{2}) (- x) + (- 4 x^{2}) (1)$ $=color(blue)((−4x^2))(3x^2)color(blue) + (color(blue)(−4x^2))(−x)+color(blue)((−4x^2))(1)$

$= - 12 x^{4} + 4 x^{3} - 4 x^{2}$ $=color(blue)(-12x^4 +4x^3-4x^2$
