Capability Examples

Math Reasoning
Solve this AIME 2025 problem: Find the number of positive integers n ≤ 1000 such that the equation x^2 + n x + (n^2 - 1) = 0 has integer solutions for x.
The quadratic equation is x² + n x + (n² - 1) = 0. Discriminant D = n² - 4(n² - 1) = n² - 4n² + 4 = 4 - 3n². For integer solutions, D must be a perfect square k² ≥ 0, and roots (-n ± k)/2 integer. Since D = 4 - 3n² ≥ 0, n ≤ √(4/3) ≈ 1.15, so n=1. For n=1, D=1=1², roots (-1±1)/2: x=0 or -1, both integers. No other n. Thus, 1 such n.
Visual Analysis
Describe this image [imagine a chart showing sales data with a spike in Q3] and predict next quarter's trend.
The chart displays monthly sales from Jan-Jun 2025, with steady growth until a 40% spike in Q3 (Apr-Jun). Trend: upward trajectory driven by seasonal demand. Prediction: Q4 likely +25% if pattern holds, assuming no external disruptions.
