See a solution process below:

To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

$(color(red)(2x) - color(red)(6))(color(blue)(8x) - color(blue)(3))$ becomes:

$(color(red)(2x) xx color(blue)(8x)) - (color(red)(2x) xx color(blue)(3)) - (color(red)(6) xx color(blue)(8x)) + (color(red)(6) xx color(blue)(3))$

$16x^2 - 6x - 48x + 18$

We can now combine like terms:

$16x^2 + (-6 - 48)x + 18$

$16x^2 + (-54)x + 18$

$16x^2 -54x + 18$

How do you multiply (2x - 6) ( 8x - 3)(2x - 6) ( 8x - 3)?
