Draw the graph of the quadratic equation x^2 + 1 = 0, observe its intersection with the x-axis, and find that there are no real solutions, thus introducing the concept of complex numbers. First, plot the function f(x) = x^2 + 1, then find the points where f(x) intersects the x-axis, which are the solutions to the equation, but since the equation has no real solutions, these points are actually complex solutions.
