Basic syntax sanity check for JSON (full parse), XML (root-element check), and YAML (real js-yaml parse) — JavaScript not included. Code never leaves your device.
x = 2 and x = 3 — discriminant 25−24 = 1, a perfect square giving two rational roots. Enter a=1, b=−5, c=6 to verify.
No real roots — the parabola never crosses the x-axis. The solver reports the complex pair instead of failing silently.
Yes — coefficients, discriminant value, and formula substitution display in order, so the working matches classroom format.
No — solving runs locally in your browser. Nothing leaves your device.
