Assess students' ability to formulate and solve quadratic models from real-world contexts using the quadratic formula and completing the square. Tasks include deriving equations for projectile motion (initial velocity, time of flight, max height) and area optimization (expressing area in one variable, finding dimensions that maximize area), solving for relevant roots, locating and interpreting the vertex, analyzing the discriminant for real solutions, checking units and realistic constraints, and clearly explaining each step and interpretation. Suitable for Grade 9–12, medium difficulty, apply-level assessment.
