To run a polynomial regression model of order 3, we need to create two pseudo-explanatory variables by squaring and cubing the values of x, respectively. This is because the model will have the form y = b0 + b1*x + b2*x^2 + b3*x^3. Therefore, we need to include x^2 and x^3 as additional variables in the model.
