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.
Elimination Shortcut: Check the extremes or test answer choices starting with C to binary search the correct magnitude.
This is a rigorous 800-level Polynomial Remainder Theorem question. If a polynomial \( P(x) \) is perfectly divisible by \( (x - r)^2 \), it means that \( x = r \) is a "double root" (a root of multiplicity 2). Mathematically, this gives us...
