Electric potential is an scalar quantity which is given by:
V = k*Q/R
R = distance between point and charge
Now net electric potential at origin will be
Vo = V1 + V2
Vo = k*q1/r1 + k*q2/r2
here,
k = 9*10^9
q1 = Q1 = 3 nC = 3*10^-9 C
q2 = -12 nC = -12*10^-9 C
from figure: r1 = 0.3 m
r2 = 0.2 m
then, Vo = (9*10^9)*[(3*10^-9)/0.3 + (-12*10^-9)/0.2]
Vo = -450 Volt
