if we have more than one independent variables? For 2 predictors, the equation of the polynomial regression becomes: 2-predictor polynomial equations where, - Y is the target, - x1, x2 are the predictors or independent variables - 𝜃0 is the bias, - and, 𝜃1, 𝜃2, 𝜃3, 𝜃4, and 𝜃5 are the weights in the
