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.
The key to unlocking this question is the Polynomial Remainder Theorem. The Remainder Theorem states that if you divide a polynomial \( P(x) \) by \( (x - c) \), the remainder is simply the value of \( P(c) \). **Step 1: Set up the first eq...
