See a solution process below:

Explanation:

To simplify, multiply each term within the parenthesis by the term outside the parenthesis:

$- 4 x (x^{2} - 8 x + 3) \Rightarrow$ $color(red)(-4x)(x^2 - 8x + 3) =>$

$(- 4 x \times x^{2}) - (- 4 x \times 8 x) + (- 4 x \times 3) \Rightarrow$ $(color(red)(-4x) xx x^2) - (color(red)(-4x) xx 8x) + (color(red)(-4x) xx 3) =>$

$- 4 x^{3} - (- 32 x^{2}) + (- 12 x) \Rightarrow$ $-4x^3 - (-32x^2) + (-12x) =>$

$- 4 x^{3} + 32 x^{2} - 12 x$ $-4x^3 + 32x^2 - 12x$
