Complex number in Mathematics (1) Definition of plural For example, if the discriminant is less than 0, the quadratic equation with one variable still has no solution, so the number set is expanded again to reach the complex range Definition: a number in the form of Z = a + bi is called complex number, where I is an imaginary unit, and I ^ 2 = I * I = - 1 (a, B are any real numbers) We call the real number a in the complex z = a + bi the real part of the imaginary Z, and record it as rez = a The real number B is called the imaginary part of the imaginary number Z, denoted as IMZ = B It is easy to know: when B = 0, z = a, then the complex number becomes a real number; When a = 0 and B ≠ 0, z = Bi, we call it pure imaginary number The set of complex numbers is represented by C. obviously, R is the proper subset of C The complex set is an unordered set, and the size order cannot be established (2) Four algorithms of complex numbers: If Z1 = a + bi, Z2 = C + Di, where a, B, C, D ∈ R, then 　　z1±z2=（a＋bi）±（c＋di）＝（a±c）＋（b±d）i, 　　（a＋bi）•（c＋di）＝（ac－bd）＋（bc＋ad）i, （a＋bi）÷(c＋di)=(ac+bd)/(c^2+d^2) +((bc-ad)/(c^2+d^2))i According to the number of certain and four operations, write the complex class 2、 Requirements and purpose of the experiment 1.

Because if n can take any number, then it will definitely have more than seven roots, but whether it is a complex number or not, it can only have seven roots at most, so you can judge that you are wrong without looking at how you solve it. Even if you can draw infinite solutions in the complex plane, it is not infinite, it is just repetition.
