Lets do this step-by step:\r
\n" ); document.write( "\n" ); document.write( " $\"3x%5E2y%2B2xy%2B5y\"$ \r
\n" ); document.write( "\n" ); document.write( "substitute $\"x=3\"$ -
\n" ); document.write( "this means we replace all x's with the number 3:\r
\n" ); document.write( "\n" ); document.write( " $\"3%283%5E2%29y%2B2%283%29y%2B5y\"$
\n" ); document.write( "which is the same as
\n" ); document.write( " $\"3%289%29y%2B2%283%29y%2B5y\"$
\n" ); document.write( "which simplifies to
\n" ); document.write( " $\"27y%2B6y%2B5y\"$ \r
\n" ); document.write( "\n" ); document.write( "now replace the y terms with $\"y=2\"$
\n" ); document.write( " $\"27%282%29%2B6%282%29%2B5%282%29\"$
\n" ); document.write( "which is the same as
\n" ); document.write( " $\"54%2B12%2B10\"$
\n" ); document.write( "and
\n" ); document.write( " $\"54%2B12%2B10=76\"$ \r
\n" ); document.write( "\n" ); document.write( "so the answer in its simplest form is 72\r
\n" ); document.write( "\n" ); document.write( "I hope this helps you.\r
