Two complex numbers z 1 = a + ib and z 2 = x + iy are equal if and only if a = x and b = y i.e., Re (z 1) = Re (z 2) and Im (z 1) = Im (z 2 ). Example One. The basic operations on complex numbers are defined as follows: (a+bi)+(c+di)=(a+c)+(b+d)i(a+bi)–(c+di)=(a−c)+(b−d)i(a+bi)(c+di)=ac+adi+bci+bdi2=(ac−bd)+(bc+ad)i a+bic+di=a+bic+di⋅c−dic−di=ac+bdc2+d2+bc−adc2+d2i In dividing a+bi by c+di, we rationalized the denominator using the fact that (c+di)(c−di)=c2−cdi+cdi−d2i2=c2+d2. If z\(_{1}\) = 5 + 2yi and z\(_{2}\) = -x + 6i are equal, find the value of x and y. Basic Concepts of Complex Numbers. Given complex numbers are m\(^{2}\) - 7m + 9ni and n\(^{2}\)i + 20i -12, m\(^{2}\) - 7m + 9ni = n\(^{2}\)i + 20i -12, â (m\(^{2}\) - 7m) + i(9n) = (-12) + i(n\(^{2}\) + 20), m\(^{2}\) - 7m = - 12 and 9n = n\(^{2}\) + 20, â m\(^{2}\) - 7m + 12 = 0 and n\(^{2}\) - 9n + 20 = 0, â (m - 4)(m - 3) = 0 and (n - 5)(n - 4) = 0. Addition is defined componentwise in a relatively standard way that extends to spaces of higher dimension. 7i are equal, then x = -5 and y = 7.
