With identical signals applied to both inputs and equal collector resistances (RC1 = RC2), the differential amplifier ideally cancels out the signals, resulting in a zero output. This is because the differential amplifier amplifies the difference between the two input signals, and if the inputs are identical, the difference is zero.
