Imaginary unit i is defined as

The imaginary unit or unit imaginary number (i) is a solution to the quadratic equation $${\displaystyle x^{2}+1=0}$$. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication. A simple example of the use of i … Zobacz więcej Being a quadratic polynomial with no multiple root, the defining equation $${\displaystyle x^{2}=-1}$$ has two distinct solutions, which are equally valid and which happen to be additive and multiplicative inverses Zobacz więcej Designating square roots of negative numbers as "imaginary" is generally credited to René Descartes, and Isaac Newton used the term as early as 1670.
