**What do we do now? Thus, i = Rene Descartes proposed a solution.**

He proposed that the solution to the equation x2 = -1 be represented by a number i where i is not a real number. Thus, i =

6
**Pure Imaginary Numbers**

For any positive real number b, where i is the imaginary unit, and bi is called a pure imaginary number.

**So let’s go back and solve**

3x = 0 x2 = - 5 x =
