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 ... WebA complex number is a number that can be written in the form a + bi a+ bi, where a a and b b are real numbers and i i is the imaginary unit defined by i^2 = -1 i2 = −1.
