1show the relation between those parameters .. ti where i = 1,2,3,4 .
11see answer is (t1+t2)(t2+t3)=-4 .. but where did t4 go [3.. please solve .. and get ruslut between them [1]
1actually u know the relation btween t1,t2,t3,t4 should be:
(t1+t4)(t4+t3)= (t1+t2)(t2+t3)
the one u gave ... is that the ans or hint ???
1answer is (t1+t2)(t2+t3)=-4 . written it earlier sky.. cn u shw a few steps hw u got t4 .. plz shw
