Calculation path
Classify the real-root behavior of a quadratic through its discriminant. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Calculation pathDelta = b^2 - 4ac Conversion resultDelta = b^2 - 4ac
What you receive
What you receive
- Discriminant from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
A must be nonzero for the coefficients to define a quadratic.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
