Prompt
How can the discriminant help with a nonlinear system?
Answer
After substitution produces a quadratic, its discriminant predicts the number of real intersections.

Prompt
Why verify solutions in both original equations?
Answer
Algebraic operations, especially squaring, can introduce invalid pairs.

MediumStudy card 7
Prompt
What is a graph best used for in a nonlinear system?
Answer
Estimating solution count and location; exact coordinates still require algebra when requested.
