Webx iy x iy = x iy (x+ iy)(x iy) = x iy x2 + y2 (2) The expression x iyappears so often and is so useful that it is given a name: it is called the complex conjugate of z = x+ iy, and a shorthand notation for it is z; that is, if z = x+ iy, then z= x iy. For example, 3 + 4i= 3 4i, as illustrated in Fig 1a . Note that z= zand z 1 + z 2 = z 1 + z 2. Web2.

WebThe solutions are z = 2 + 3 i and z = − 2 − 3 i. Completing the square gives ( z + 2) 2 − 4 = − 12 + 6 i so ( z + 2) 2 = − 8 + 6 i. Writing z + 2 = x + i y gives the equations x 2 − y 2 = − 8 and 2 x y i = 6 i. By inspection, we can take x = 1, y = 3 or x = − 1, y = − 3. The solutions are therefore − 1 + 3 i and − 3 − 3 i.
