    If you are doing to use them as inverting amplifiers, you can add another resistor on the inverting input and create a summing amplifier. Then use a potentiometer to adjust the voltage on this resistor, when the input signal resistor is tied to ground, as the output to have zero volts.
    What are you going to do with these op amps?

    i actually was using alot of amplifiers in my project so i thought that instead of using single amp ic i should use something that contains more than one ic so that i could get rid of the power supplies to all.....

    If you need a trim, you are almost stuck with singles. Or find better op amps that don't have offset problems so you don't need trimming.

    Many cases you don't even need to null it, let's see the schematic...
