Webb3 dec. 2024 · The question tells us that (n + 2)! = n! (an² + bn + c) So, we can write: (n!) (n + 2) (n + 1) = n! (an² + bn + c) Divide both sides by n! to get: (n + 2) (n + 1) = an² + bn + c. Use FOIL to expand left side: n² + 3n + 2 = an² + bn + c. In other words: 1 n² + 3 n + 2 = a n² + b n + c. So, a = 1, b = 3 and c = 2. This means abc = (1) (3 ...
