SOLVE 3x = 0 3x 2 = -15 x 2 = - 5 x = What do we do now?

5
Rene Descartes proposed a solution. He proposed that the solution to the equation x 2 = -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.

7
So lets go back and solve 3x = 0 x 2 = - 5 x =
