Real and Imaginary RootsIn this chapter we give an explicit description of the root system ∆ of a Kac-Moody algebra g(A). Our main instrument is the notion of an imaginary root, which has no counterpart in the finite-dimensional theory.doi:10.1007/978-1-4757-1382-4_5Victor G. Kac...
Descartes' rule of signs is used to find the number of real and imaginary roots. Real roots can be positive or negative. The value of positive roots depends on the number of changes in signs of the polynomial f(x). Similarly, the value of the negative root depends on the number...

Therefore, a cubic equation can have up to 3 complex roots, which may be a combination of real and imaginary roots. Can a cubic equation have an odd number of real roots? Yes, a cubic equation can have an odd number of real roots. This occurs when the discriminant is positive and ...
According to the problem, coefficients of the required quadratic equation arereal and its one root is -2 + i.We know in a quadratic with real coefficients imaginary roots occur inconjugate pairs).Since equation has rational coefficients, the other root is -2 - iNow, the sum of the root...
