The coefficients of the binomial expansion of (1 + x)n for a positive integer n is the nth row of Pascal's triangle.
Well, honey, it ain't rocket science. To multiply 4n by 2n, you simply multiply the coefficients (4 and 2) to get 8, and then multiply the variables (n and n) to get n^2. Put 'em together and you've got 8n^2. Easy peasy lemon squeezy!
