Thank you so much dude. My professor somewhat went over how to do this in his lecture with the 1st degree equation of a line, but there was basically 0 material on how to do it with polynomials. This makes a ton of sense and helped me out.

That's very much wonderful work, but I have a queried that could you please print chi-sq value of these polynomials, for model comparisons among these polynomials fit.
