Solving a Polynomial Functional Equation: Compute f(10) | Step-by-Step Solution
In this video, we solve an intriguing problem involving a non-constant polynomial f(x) that satisfies the functional equation: f(f(x)) + f(x) = (f(x))². Our goal is to compute f(10).
We start by analyzing the degree of the polynomial, assume a quadratic form, and then compare coefficients to find the exact expression for f(x). Finally, we substitute x = 10 into the polynomial to arrive at the solution. Watch this step-by-step breakdown to see how we solve it!
