[QUOTE="Math Amateur, post: 5500462, member: 203675"] I am trying to gain an understanding of the basics of elementary algebraic geometry and am reading Dummit and Foote Chapter 15: Commutative Rings and Algebraic Geometry ... At present I am focused on Section 15.1 Noetherian Rings and Affine Algebraic Sets ... ... I need someone to help me to fully understand the reasoning/analysis behind one of the statements in Example (3) on Page 660 of D&F ... On page 660 (in Section 15.1) of D&F we find the following text and examples (I am specifically focused on Example (3)):[ATTACH=full]188579[/ATTACH] In the above text, in Example (3), we find the following: "... ... For any polynomial ##f(x,y) \in k[x,y]## we can write ##f(x,y) = f_0(x) + f_1(x)y + (x^3 - y^2) g(x,y).##"Can someone explain ( [ATTACH=full]202964[/ATTACH] slowly and carefully) exactly how/why this is true ... ... Peter==================================================== In order for readers of the above post to understand the context of the question and the notation employed I am providing the introductory pages on affine algebraic sets in the D&F text ... ... as follows: [ATTACH=full]202965[/ATTACH] [ATTACH=full]202966[/ATTACH] [ATTACH=full]202967[/ATTACH] [/QUOTE]
