# Palindromic polynomial

**Tutor description**

A polynomial is palindromic, if the sequence of its coefficients are a palindrome. Some examples of palindromic polynomials are: (x + 1)2 = x2 + 2x + 1 (x + 1)3 = x3 + 3x2 + 3x + 1. Generally, the expansion of (x + 1)n is palindromic for all n (can see this from binomial expansion)
