Complex or imaginary numbers - A complete course in algebra
Complex numbers have the form a + bi, where i2 = -1. Comlex numbers allow one to solve all polynomial equations, including those such as x2 + 1 = 0 and x2 + x + 1 = 0, which do not have real roots. The two parts of a complex number a and bi are called its real and imaginary parts respectively.
