Opamp have one positive terminal & one negative terminal. That's why it is called one terminal is inverting & 2nd is non inverting.

Why v2 negative?

Vo = -Rf/R1*V1-V2.
= -100/100*1-(-1) V.
= -2 V.
= -100/100*1-(-1) V.
= -2 V.

Vo = -(Rf/R1)(V1-V2).

Vo = (-100k/100k)*1+(1+100k/100k)*{(-1)*(20k/(20k+20k))}.
= -1*1+2*(-1)/2.
= -1-1.
= -2 Answer.
= -1*1+2*(-1)/2.
= -1-1.
= -2 Answer.

R1 = 100K.
R2 = 100K.
Vo = R2/R1(V2-V1).
Vo = 100K/100K(-1-1).
Vo = 1(-2).
Vo = -2 Answer.
R2 = 100K.
Vo = R2/R1(V2-V1).
Vo = 100K/100K(-1-1).
Vo = 1(-2).
Vo = -2 Answer.

Since its a circuit of subtractor whose o/p voltage is = v1-v2= -2*v2 = -2*1 = -2.

/* The above example -v(inverting terminal) get more voltage than +v(non inverting) terminal*/
Vout = (v1-v2) * (-(rf/r1)).
= (1-(-1))*(-(100/100)).
= -2*1.
= -2.
Vout = (v1-v2) * (-(rf/r1)).
= (1-(-1))*(-(100/100)).
= -2*1.
= -2.

Vo = RF(V2-V1)/R1.
Vo = (-1-1)100k/100k
Vo = -2.
Vo = (-1-1)100k/100k
Vo = -2.

Vo=rf/r1(v2-v1).
Vo=100k/100k(-1-1)=-2.
Vo=100k/100k(-1-1)=-2.
