एक ऑपरेशनल एम्पलीफायर (op-amp) का कुल आउटपुट ऑफसेट वोल्टेज मुख्य रूप से किन प्रभावों का फलन होता है?

The input impedance and bandwidth of an ideal operational amplifier (OP-AMP) respectively are:

For an ideal non-inverting operational amplifier with a voltage gain of 2, if the non-inverting input voltage is 2 V and the output voltage is 10 V, what is the inverting input voltage assuming the op-amp is operated with differential inputs in an open-loop or non-standard configuration where output Vout = A(V1 - V2) and A = 2, V1 = 2 V?
