Quadratic Discriminant from Coefficients Calculator
Quadratic Discriminant from Coefficients. Example: A: 1 number, B: -3 number, C: 2 number gives 1 number. Dimensionless coefficients with a>0; signed discriminant returned, no complex roots claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible.
Dimensionless coefficients with a>0; signed discriminant returned, no complex roots claim. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Complete the square for quadratic to identify discriminant.
Accepted inputs: A: 0.001 to 10,000 number; B: -10,000 to 10,000 number; C: -10,000 to 10,000 number.
How the calculation works
D=b²-4ac
Worked example
With a 1 number, b -3 number, c 2 number, quadratic discriminant from coefficients is 1 number.
