See the entire simplification process below:

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

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

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

$x^2 - 8x + 3x - 24$

We can now combine like terms:

$x^2 + (-8 + 3)x - 24$

$x^2 - 5x - 24$

How do you simplify (x + 3)(x - 8) (x + 3)(x - 8) ?
