See the entire solution process below:

Explanation:

First, we can rewrite this expression as:

(8 - m)(8 - m)

Then, to multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

(color(red)(8) - color(red)(m))(color(blue)(8) - color(blue)(m)) becomes:

(color(red)(8) xx color(blue)(8)) - (color(red)(8) xx color(blue)(m)) - (color(red)(m) xx color(blue)(8)) + (color(red)(m) xx color(blue)(m))

64 - 8m - 8m + m^2

We can now combine like terms:

64 + (-8 - 8)m + m^2

64 - 16m + m^2

m^2 - 16m + 64
