Use Pascal's Triangle to expand each binomial.
\n" ); document.write( "(x-3)^3\r
\n" ); document.write( "\n" ); document.write( "Here's some 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\r
\n" ); document.write( "\n" ); document.write( "This 4th row is what we need to expand $\"%28x-3%29%5E3\"$ which is:\r
\n" ); document.write( "\n" ); document.write( " $\"x%5E3%2B3x%5E2%28-3%29%2B3x%28-3%29%5E2%2B%28-3%29%5E3+=+x%5E3-9x%5E2%2B27x-27\"$ . \n" ); document.write( "
