Can anyone explain how a tda2030 bridge amplifier works.the circuit is in its datasheet. Works on 12v dual supply. Produce 35watts RMS. I'm a beginner. Please.

The output of the top amplifier feeds the negative input of the bottom amplifier so their output voltage swings are doubled. With a +/-12V power supply The top amplifier output swings to a peak of +9V when the output of the bottom amplifier swings to a peak of -9V. Then the 8 ohm speaker gets 20W RMS just before clipping. When the supply is +/-16V and the distortion is very high then the output is 34W.

So the output of top amplifier is send to the input of second amplifier. Which value of resistor is needed to connect them?

Why are you asking about resistor values that are all shown on the datasheet for the TDA2030 and the TDA2030A??
