= PolynomialRing(QQ) f = x^2 - 3*x + 2 print(f(1))
R.The result of this code would be x^3 + 3x^2 - 6x + 3. In summary, PolynomialRing is a package library that is used for performing algebraic computations with polynomials. It is a part of the SageMath package for Python. The examples shown above illustrate some of the basic functionalities of this package library.
= PolynomialRing(QQ) f = x^2 - 3*x + 2 g = x^3 + 2*x^2 - 3*x + 1 h = f + g print(h)
