State
One object wears three role-fixed names — zero of the function, x-intercept of the graph, solution of f(x) = 0 — and the discriminant counts them.
Show
x² − 4x + 3 factors as (x − 1)(x − 3): zeros 1 and 3, intercepts to match, discriminant 4 as promised.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
