Webx 2 + 2i*xy - y 2 + i = 0. Keeping in mind that two complex numbers are equal if and only if the real parts are equal to each other and the imaginary parts are equal to each other, we get two equations: x 2 - y 2 = 0. 2xy + 1 = 0. From the first equation, it is clear that x=y or x=-y. Substituting into the second, we have 2x 2 + 1 = 0 or -2x 2 ... WebAug 30, 2024 · A complex number is defined as the addition of a real number and an imaginary number. It is represented as “z” and is in the form of (a + ib), where a and b are real numbers and i is an imaginary unit whose value is √ (-1). The real part of the complex number is represented as Re (z), and its imaginary part is represented as Im (z).
