You've got the right formula.
\n" ); document.write( "17^2=x^2+(x+2)^2
\n" ); document.write( "289=x^2+x^2+4x+4
\n" ); document.write( "289=2x^2+4x+4
\n" ); document.write( "2x^2+4x+4-289=0
\n" ); document.write( "2x^2+4x-285=0
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "x=(-4+-sqrt[4^2-4*2*-285])/2*2
\n" ); document.write( "x=(-4+-sqrt[16+2,280])/4
\n" ); document.write( "x=(-4+-sqrt2,296)/4
\n" ); document.write( "x=(-4+-47.917)/4
\n" ); document.write( "x=(-4+47.917)/4
\n" ); document.write( "x=43.917/4
\n" ); document.write( "x=10.979 ans.
\n" ); document.write( "x=(-4-47.917)/4
\n" ); document.write( "x=-51.917/4
\n" ); document.write( "x=-12.979 ans. \n" ); document.write( "

\n" );
