About this app
Quadratic Solver solves all equations ax² + bx + c = 0 and displays the complete solution, written out like in high school. Ideal for checking an exercise, reviewing before a test, or understanding each step.
Enter the coefficients a, b, and c: the solution updates in real time.
WHAT THE APPLICATION DISPLAYS
• The calculation of the discriminant Δ = b² − 4ac, with substitution of values
• The simplified discriminant Δ′ when b is even
• The exact and simplified solutions, for example (3 + 2√3)/3, with an approximate value
• The solution set S = { x₁ ; x₂ }
• Verification by the sum and product of the roots
• Factoring a(x − x₁)(x − x₂)
• The vertex, vertex, and axis of symmetry of the parabola
• The sign chart of the quadratic trinomial
• The graph of the parabola, with the roots and vertex
ALL CASES COVERED
• Δ > 0: two distinct real solutions
• Δ = 0: a double solution
• Δ < 0: no real solution, with solutions in ℂ as an option
• a = 0: solving the first-degree equation
PRACTICE IN CLASS AND AT HOME
• Integer, decimal (0.5), or fractional (3/4) coefficients
• Ready-to-use examples and a "Random Equation" button for practice
• Light and dark themes
• Works offline Internet
