What is it?
- Simple explanation: Mathematical shortcuts created by François Viète that prove how the coefficients of a polynomial strictly define the sum and product of its roots.
- Why it matters in cubic equations: It acts as an incredibly powerful verification tool. If you solve an equation, adding the three roots together *must* equal -b/a. If it doesn't, a mistake was made!
Formula / Method
- Formulas for Cubic Roots r_1, r_2, r_3: * Sum of roots: r_1 + r_2 + r_3 = -\frac{b}{a} * Pairwise product sum: r_1r_2 + r_1r_3 + r_2r_3 = \frac{c}{a} * Total product: r_1 \cdot r_2 \cdot r_3 = -\frac{d}{a}
How To Use

- Review the three generated outputs showing root relationships.
- Use these facts to verify your own hand-calculated roots.
Key Features
- Highly robust outputs formatted clearly.
- Instant generation without invoking deeper algorithms.
- Retains exact fraction formatting for pure accuracy.

Example Concept
For 2x³ - 8x² + 6x - 4 = 0: Sum of roots = -(-8) / 2 = 4. Pairwise sum = 6 / 2 = 3. Product of roots = -(-4) / 2 = 2.

Does Vieta's rule apply to complex roots?
Yes! The rules of Vieta apply perfectly even when the roots involve imaginary numbers. The complex parts simply cancel each other out during addition.
Does this tell me what my roots actually are?
No, it only tells you how they relate to each other as a complete set.
Why is \(a\) in the denominator of everything?
Because Vieta's formulas inherently rely on normalizing the polynomial (making the leading coefficient 1) first.
