Explanation:

We can rewrite this expression as:

(color(red)(8) - color(red)(9x))(color(blue)(8) - color(blue)(9x)) which becomes:

(color(red)(8) xx color(blue)(8)) - (color(red)(8) xx color(blue)(9x)) - (color(red)(9x) xx color(blue)(8)) + (color(red)(9x) xx color(blue)(9x))

64 - 72x - 72x + 81x^2

We can now combine like terms:

64 - (72 + 72)x + 81x^2

64 - 144x + 81x^2

81x^2 - 144x + 64
