See the entire 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.

$(color(red)(x) + color(red)(6))(color(blue)(x) - color(blue)(6))$ becomes:

$(color(red)(x) xx color(blue)(x)) - (color(red)(x) xx color(blue)(6)) + (color(red)(6) xx color(blue)(x)) - (color(red)(6) xx color(blue)(6))$

$x^2 - 6x + 6x - 36$

We can now combine like terms:

$x^2 + (-6 + 6)x - 36$

$x^2 + 0x - 36$

$x^2 - 36$

How do you multiply (x + 6)(x − 6) (x + 6)(x − 6) ?
