my initial signal in from -1 to 1 volt, and with two resistors i do an amplitude divisor but from 0 to 500mV, and i want from -250mV to 250mV. how i do it?

A simple two resistor potential divider will do exactly that, if the input is positive the output will be positive, is the input is negative the output will be negative. With a resistor ratio of 3 to 1, and an input of -1V to +1V, the output will be -250mV to +250mV.
