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 brilliantly deceptive question. At first glance, you might think you need to expand \( (x - 2)^2 (x + 1)^2 \) into a degree-4 polynomial, match the coefficients to \( a, b, c, \) and \( d \), and then add them all together. While ...
