Define Complex Numbers and Quadratic Equations.

Complex number is of the form a +ib where a is real part and b is imaginary part. Here i = √ -1. The complex number x + iy  can be represented  geometrically as the unique point  P(x, y) in the XY-plane and vice-versa. Plane with complex number assigned to each of its point is called complex or Argand plane. The addition of complex numbers satisfies the following properties: Closure law: z1 + z2 = complex Number, Commutative law: z1 + z2 = z2 + z1, Associative law: (z1 + z2) + z3 = z1 + (z2 + z3). Additive identity: z + 0 = z. Additive inverse: z + (–z) = 0.
