Use this formulas

\n" ); document.write( "2. $\"%28n%28n-3%29%29%2F%282%29\"$ \r
\n" ); document.write( "\n" ); document.write( "to find number of non-intersecting (formula 1.) and intersecting (formula 2.) diagonals\r
\n" ); document.write( "\n" ); document.write( "if $\"n+\"$ $\"is\"$ $\"the\"$ $\"+number\"$ $\"+of\"$ $\"+vertexes\"$
\n" ); document.write( "you have $\"n+=+8\"$
\n" ); document.write( "
\n" ); document.write( "if you are counting non-intersecting diagonals, will be
