Replace every x with 2. Then evaluate with a calculator or use pencil/paper\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2x%5E2%2B3x-1\"
\n" ); document.write( "\"2%282%29%5E2%2B3%282%29-1\" Replace every x with 2
\n" ); document.write( "\"2%284%29%2B3%282%29-1\"
\n" ); document.write( "\"8%2B6-1\"
\n" ); document.write( "\"14-1\"
\n" ); document.write( "\"13\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "So when \"x+=+2\", the value of \"2x%5E2%2B3x-1\" is 13
