Solving a Fun Cubic Equation (Polynomial of degree 3)
There is a number that you can cube, then divide by 2, and the result is that same number. In fact, there are THREE numbers this works for. In this video, we solve this problem, using some pretty simple algebra tools.
This video demonstrates how to use polynomial factoring, and apply the fundamental theorem of algebra to show the 3 solutions to the equation x^3 / 2 = x, for real numbers.
