This tool helps you solve algebra problems step-by-step to understand the solutions better.
Algebra 2 Calculator
This calculator solves quadratic equations of the form ax2 + bx + c = 0.
How to Use:
Enter values for a, b, and c into the input fields. The calculator will compute the discriminant and the roots of the equation, if they exist.
How it Works:
The calculator uses the quadratic formula x = [-b ± sqrt(b2 – 4ac)] / 2a to find the roots. The discriminant (Δ) is computed as b2 – 4ac. Depending on the value of the discriminant, the roots can be real and different (Δ > 0), real and same (Δ = 0), or complex (Δ < 0).
Limitations:
This calculator only works for quadratic equations where a ≠ 0. If a is zero, the equation is linear and the calculator will notify you. Ensure all inputs are valid numbers to obtain accurate results.
