let x be first odd integer, then x+2 is the next one
\n" ); document.write( ":
\n" ); document.write( "x^2 +(x+2)^2 = 74
\n" ); document.write( ":
\n" ); document.write( "x^2 +x^2+4x+4 = 74
\n" ); document.write( ":
\n" ); document.write( "2x^2 +4x -70 = 0
\n" ); document.write( ":
\n" ); document.write( "x^2 +2x -35 = 0
\n" ); document.write( ":
\n" ); document.write( "(x+7) * (x-5) = 0
\n" ); document.write( ":
\n" ); document.write( "x = -7 and x = 5
\n" ); document.write( ":
\n" ); document.write( "****************************************************
\n" ); document.write( "we want x = 5 because x > 0 and x+2 > 0
\n" ); document.write( "Our two consecutive positive odd numbers are 5 and 7
\n" ); document.write( "****************************************************
\n" ); document.write( ":
\n" ); document.write( "note that 5^2 + 7^2 = 25 + 49 = 74
