The condition for only one root in interval (d,e) is f(d)*f(e) less than 0 but if ‘d’ itself is a root and the other root lies in the interval (d,e) then f(d)*f(e) = 0 .Then why not is the condition f (d)*f(e) less than or equal to 0??
Dear student There is open bracjet on d hence d can not be counted in interval RegardsArun(askIITians forum expert)
But I am talking about ‘d’ to be the second root and the first root to be lying in the interval (d,e) then the condition changes to f(d)*f(e) = 0.Then why not is the necessary condition f (d)*f(e) less than or equal to 0??
