Solve for all real values of x

                        x² + 4 = 0
                      -4.  -4

                       x² = -4

                 √x² = ± √(-4)

                 x = ± 2i

          Solutions: x = 2i, x = -2i

Since the solutions are imaginary, there are no real solutions for this equation.
