WebFirst of all, real part of any complex number (a+ib) is represented as Re (a + ib) = a and imaginary part of (a +ib) is represented as Im (a+ib) = b. Also, when two complex numbers are equal, their corresponding real parts and imaginary parts must be equal. Therefore, if a + ib = c + id, then Re (a+ib) = Re (c+id) and Im (a+ib) = Im (c+id) WebMCQs Based on Quadratic Equation and Complex Number. Started on 7:30 AM.
