See the solution process below:

Multiply each term within the parenthesis by the term outside the parenthesis:

$5 x (3 x^{2} - x + 3) \to$ $color(red)(5x)(3x^2 - x + 3) ->$

$(5 x \times 3 x^{2}) - (5 x \times x) + (5 x \times 3) \to$ $(color(red)(5x) xx 3x^2) - (color(red)(5x) xx x) + (color(red)(5x) xx 3) ->$

$15 x^{3} - 5 x^{2} + 15 x$ $15x^3 - 5x^2 + 15x$

How do you simplify 5x(3x2−x+3)5x(3x^2 - x + 3)?
