In mathematics, a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol called the imaginary unit, and satisfying the equation i² = −1. Because no "real" number satisfies this equation, i was called an imaginary number by René Descartes.

Answer 2

Answer:

Step-by-step explanation:

Complex numbers are numbers that consist of two parts — a real number and an imaginary number. ... The standard format for complex numbers is a + bi, with the real number first and the imaginary number last. Because either part could be 0, technically any real number or imaginary number can be considered a complex number.
