R^2-10r+16<0;
by factoring:;
[r-2][r-8]=0;

roots; r=2 ; r=8;
checking intervals:..(r-2)(r-8)          <0
r<2....                      (-)(-)=+; +>0....does not satisfy the ineaqualty;
2<r<8..                    (+)(-)=- ; -<0..  satisfy the ineq; 
r>8                           (+)(0)=0; 0<0..does not satisfy the ineq;

the solution set:{x/ 2<r<8};

-------I---------o......r.............o-------; this would be your plot in domain
