Is a Polynomial regression in Excel the same as a Quadratic regression? If so, how many 'Orders' do I use? Thanks.

Answers:
It can be the same.
Quadratic regression = 2nd order polynomial regression. Therefore use a polynomial regression with 2 'orders'.
A 1st order polynomial is linear (the graph is a straight line), a 2nd order polynomial is quadratic (1 reflex point - like an arc), a 3rd order polynomial is cubic (2 reflex points- like an "S").
No, polynomila regression adjusts a polynomial to a set of data. You chopse the degree of the polynomial. You mean that Excel function availabel in chats, right?
Quadratic is more restrictive than polynomial.

You speak, of quadratic regression if you have y = kx^2 The dependent variable y is a function which is in square of X

In polynomial the regression takes the form of a polynomial degree higher than 2

ex : y = a x^4 + bx^3 +,,,, is a polynomial regression order 4
