Let one number is $\"x\"$ . Then another number is $\"x-4\"$ .
\n" ); document.write( "Then:
\n" ); document.write( " $\"x%5E2+-+%28x-4%29%5E2+=+80\"$
\n" ); document.write( " $\"x%5E2+-+%28x%5E2+-+8x+%2B+16%29+=+80\"$
\n" ); document.write( "Simplify this equation:
\n" ); document.write( " $\"x%5E2+-+x%5E2+%2B+8x+-+16+=+80\"$
\n" ); document.write( " $\"8x+-+16+=+80\"$
\n" ); document.write( " $\"8x+=+96\"$
\n" ); document.write( " $\"x+=+96%2F8+=+12\"$
\n" ); document.write( "Then $\"x-4+=+12-4+=+8\"$ .\r
\n" ); document.write( "\n" ); document.write( "Answer: one number is 12 and another number is 8. \n" ); document.write( "
