$\"sqrt%283x%2B4%29+-+sqrt%282x-4%29+=2\"$
\n" ); document.write( " $\"sqrt%283x%2B4%29+=+sqrt%282x-4%29+%2B+2\"$
\n" ); document.write( "Square both sides
\n" ); document.write( " $\"3x%2B4+=+%282x-4%29+%2B+4sqrt%282x-4%29+%2B+4+=+2x+%2B+4sqrt%282x-4%29\"$
\n" ); document.write( " $\"x%2B4+=+4sqrt%282x-4%29\"$
\n" ); document.write( "Square again
\n" ); document.write( " $\"x%5E2+%2B+8x+%2B+16+=+16%282x-4%29+=+32x+-+64\"$
\n" ); document.write( " $\"x%5E2+-+24x+%2B+80+=+0\"$
\n" ); document.write( "(x-4)(x-20) = 0
\n" ); document.write( "x = 4
