$\"sqrt%285x%2B39%29=x%2B3\"$
\n" ); document.write( "start by squaring both sides to get:
\n" ); document.write( " $\"5x%2B39+=+%28x%2B3%29%5E2\"$
\n" ); document.write( " $\"5x%2B39+=+%28x%2B3%29%28x%2B3%29\"$
\n" ); document.write( "FOIL the right side:
\n" ); document.write( " $\"5x%2B39+=+x%5E2%2B6x%2B9\"$
\n" ); document.write( " $\"39+=+x%5E2%2Bx%2B9\"$
\n" ); document.write( " $\"0+=+x%5E2%2Bx-30\"$
\n" ); document.write( "factoring the right:
\n" ); document.write( " $\"0+=+%28x%2B6%29%28x-5%29\"$
\n" ); document.write( "x = {-6, 5}\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
