We show that there is a relationship between the coefficient of the 2-Fibonacci polynomials and Pascal's triangle. We give some identities of the 2-Fibonacci polynomials. Afterwards, we compare the polynomials with known Fibonacci polynomials. We also express 2-Fibonacci polynomials by the Fibonacci polynomials. Furthermore, we prove some theorems related to the polynomials. Also, we introduce the derivative of the 2-Fibonacci polynomials.</dc:description><dc:publisher>BULGARIAN ACAD SCIENCE</dc:publisher><dc:date>2018</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/16778</dc:identifier><dc:identifier>https://doi.org/10.7546/nntdm.2018.24.3.47-55</dc:identifier><dc:identifier>1310-5132</dc:identifier><dc:language>en</dc:language><dc:relation>NOTES ON NUMBER THEORY AND DISCRETE MATHEMATICS</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/16778</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
