This paper is concerned with the non-trivial rational solutions for the generalized Abel equation x = A(t)xn + B(t)xm + C(t)x, where m, n ∈ N, n > m > 1 and A(t), B(t),C(t) ∈ R[t]. A solution is called a non-trivial rational solution if it takes the form x = q(t)/p(t), where p, q are polynomials in t and gcd(p, q) = 1 with deg(p) ≥ 1. In this work, we provide an upper bound on the number of the real and complex non-trivial rational solutions for the mentioned generalized Abel equation.
