Identify the quadratic form: consider converting to vertex form \( y = a(x-h)^2 + k \) or using \( x = - rac{b}{2a} \) to find the line of symmetry.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
This problem masterfully combines the Complex Conjugate Root Theorem with Polynomial Identity. Step 1: Understand the roots. The problem tells us that \( x = 1 + i \) is a root of \( P(x) \). Because the polynomial has explicitly *real cons...
