You can do a bunch of algebra to solve
\n" ); document.write( " $\"n%5E2+%2B+%28n%2B2%29%5E2+=+20\"$
\n" ); document.write( "Or you can use a little 'common sense' and realize
\n" ); document.write( "- number squared are always positive
\n" ); document.write( "- 20 is a small number (between 4^2 and 5^2
\n" ); document.write( "- so use trial and error with even numbers
\n" ); document.write( "Try 2 and 4
\n" ); document.write( "2^2 = 4
\n" ); document.write( "4^2 = 16
\n" ); document.write( "4+16= 20
\n" ); document.write( "done \n" ); document.write( "
