ans: x (- ,3)(4,)-{1} soln: bringing 1 2 the LHS -X^2+5X-4/(X-1)(X-3)<0 MULIPLY BY - AND REVERSE SIGN OF INEQUALITY (X^2-5X+4)/(X-1)(X-3)>0 (X-1)(X-4)/(X-1)(X-3)>0 X is NOT = 1 as fn will b undefined (x-3)(x-4)>0 x belongs to (-inf , 3) U(4, inf)-{1} P.S. X is same as x(pls dont mind the capital fonts)
