if i put x=1 on your function f(1) doesnt equal zero how you get f(1)=0 ??

i cant see the equation that if i will put x=1 i will get 0 ?
there is no such hypothesis in the posted question ??

ok if f(0)=f(1) then there is a point c for which f'(c)=0 0<c<1 but its not a solution for f(x) its an extreme point ??

so you take a function which is an anti derivative of my given equation that i need find solution to. so the extreme point of f(x) is the solution of f'(x) thanks
Yes, finally you understand.
