1st integer = x
\n" ); document.write( "2nd integer = x+2
\n" ); document.write( "======================
\n" ); document.write( "x(x+2)=168
\n" ); document.write( " $\"x%5E2+%2B+2x+=+168\"$
\n" ); document.write( " $\"x%5E2+%2B+2x-168=0\"$
\n" ); document.write( "(x+14)(x-12)=0
\n" ); document.write( "x+14=0
\n" ); document.write( "x=-14
\n" ); document.write( "x-12=0
\n" ); document.write( "x=12
\n" ); document.write( "=================
\n" ); document.write( "So we end up with 2 possibilities;
\n" ); document.write( "x = 12 or x = -14
\n" ); document.write( "Now we need our second;
\n" ); document.write( "x + 2 = 12+2=14
\n" ); document.write( "x+2 = -14+2=-12
\n" ); document.write( "====================
\n" ); document.write( "When x = 12, the second integer = 14
\n" ); document.write( "When x = -14, second integer = -12
\n" ); document.write( ":)
\n" ); document.write( " \n" ); document.write( "

\n" );
