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.

$(color(red)(x) + color(red)(5))(color(blue)(x) - color(blue)(2))$ becomes:

$(color(red)(x) xx color(blue)(x)) - (color(red)(x) xx color(blue)(2)) + (color(red)(5) xx color(blue)(x)) - (color(red)(5) xx color(blue)(2))$

$x^2 - 2x + 5x - 10$

We can now combine like terms:

$x^2 + (-2 + 5)x - 10$

$x^2 + 3x - 10$

How do you multiply the expression (x + 5)(x - 2)(x + 5)(x - 2)?
