See a solution process below:

Explanation:

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

(color(red)(p) + color(red)(4))(color(blue)(p) - color(blue)(15)) becomes:

(color(red)(p) xx color(blue)(p)) - (color(red)(p) xx color(blue)(15)) + (color(red)(4) xx color(blue)(p)) - (color(red)(4) xx color(blue)(15))

p^2 - 15p + 4p - 60

We can now combine like terms:

p^2 + (-15 + 4)p - 60

p^2 + (-11)p - 60

p^2 - 11p - 60
