\n" ); document.write( "√(2x+1)+ √(x+4) = 3
\n" ); document.write( "==============
\n" ); document.write( "Square both sides
\n" ); document.write( "\"2x%2B1+%2B+x%2B4+%2B+2sqrt%282x%2B1%29%2A%28x%2B4%29+=+9\"
\n" ); document.write( "\"2sqrt%282x%2B1%29%2A%28x%2B4%29+=+4+-+3x\"
\n" ); document.write( "----
\n" ); document.write( "Square again
\n" ); document.write( "\"4%282x%2B1%29%2A%28x%2B4%29+=+16+-+24x+%2B+9x%5E2\"
\n" ); document.write( "\"8x%5E2+%2B+36x+%2B+16+=+16+-+24x+%2B+9x%5E2\"
\n" ); document.write( "\"x%5E2+-+60x+=+0\"
\n" ); document.write( "x = 0 using the positive values
\n" ); document.write( "-------
\n" ); document.write( "x = 60 using the negative values
\n" ); document.write( " \n" ); document.write( "
\n" );
