Solution:\r
\n" ); document.write( "\n" ); document.write( "Let 'a' and 'b' are the 2 numbers.
\n" ); document.write( "Given : a * b = -240 --------eq.1
\n" ); document.write( " a + b = 34 or b = 34 - a --------eq.2\r
\n" ); document.write( "\n" ); document.write( "Put 2 in 1, we get\r
\n" ); document.write( "\n" ); document.write( "a (34 - a ) = -240\r
\n" ); document.write( "\n" ); document.write( "34a - a^2 + 240 = 0\r
\n" ); document.write( "\n" ); document.write( "\"a%5E2+-+34+a+-+240+=+0+\"
\n" ); document.write( "Solving the quadratic equation
\n" ); document.write( "\"a%5E2+-+40a+%2B+6a+-+240+=+0\"
\n" ); document.write( "\"+a%28a-40%29+%2B6%28a+%2B+40%29+=+0\"
\n" ); document.write( "\"%28a-40%29%28a%2B6%29=0\"\r
\n" ); document.write( "\n" ); document.write( "a = 40 or a = -6\r
\n" ); document.write( "\n" ); document.write( "b = -6 or 40
\n" ); document.write( "
\n" );
