👉 In mathematics, a "hegira" is a polynomial of degree 4. It is also known as a 4th degree polynomial or a quartic polynomial in algebraic number theory. A 4th degree polynomial can be defined as a polynomial with degree 4, and it has the form: \[ f(x) = ax^4 + bx^3 + cx^2 + dx + e \] where \(a\) is not equal to zero. For example, consider the
