I want to solve this integration for time where t= 0:1

By the way, you should check the variables in your function, and the integration variable. I assumed dt really meant dx to you.

This is how you should try:
syms x
f=((1-2*x).^2)/( (x-x.^2).^2 )
int(f)
ans =
2*log(x - 1) - 2*log(x) + (2*x - 1)/(- x^2 + x)
int(f,0,1)
ans =
Inf

Dear Alberto
Many thanks but I want to ask you if you noticed that I want to integrate for (t) not for (x) !

I've notices, i just thought it was a typo. Do this then:
syms x t
f=((1-2*x).^2)/( (x-x.^2).^2 )
int(f,t,0,1)
ans =
(2*x - 1)^2/(x - x^2)^2
