Use Pascal's Triangle to expand each binomial.
\n" ); document.write( "(x+y)^8\r
\n" ); document.write( "\n" ); document.write( "Here's the first 9 rows of Pascal's triangle:\r
\n" ); document.write( "\n" ); document.write( "1
\n" ); document.write( "1 1
\n" ); document.write( "1 2 1
\n" ); document.write( "1 3 3 1
\n" ); document.write( "1 4 6 4 1
\n" ); document.write( "1 5 10 10 5 1
\n" ); document.write( "1 6 15 20 15 6 1
\n" ); document.write( "1 7 21 35 35 21 7 1
\n" ); document.write( "1 8 28 56 70 56 28 8 1\r
\n" ); document.write( "\n" ); document.write( "The 9th row gives us the coefficients for $\"%28x%2By%29%5E8\"$ :\r
