Look at this math chad flexing on us with the difference of powers formula! The top panel shows the intimidating polynomial a n - b n , and our hero is just casually holding it like "challenge accepted." Then BAM! In the second panel, he's factored it into that beautiful summation form (a-b)∑a n-1-k b k . That smug little smile says it all - "Yeah, I factor polynomials at parties. No big deal." This is basically mathematical weightlifting, except instead of protein shakes, this guy drinks coffee with chalk dust sprinkled on top.
