\n" ); document.write( "ans:-\r
\n" ); document.write( "\n" ); document.write( "let the ones digit is x
\n" ); document.write( "then tens digit is x+3
\n" ); document.write( "as per question x^2+(x+3)^2=29
\n" ); document.write( "or 2x^2+6x-20=0
\n" ); document.write( "or 2x^2+10x-4x-20=0
\n" ); document.write( "or 2x(x+5)-4(x+5)=0
\n" ); document.write( "or (2x-4)(x+5)=0
\n" ); document.write( "or x=-5 or 2 ans
\n" ); document.write( "
\n" );
