How the Quadratic Equation Solver Works?
A quadratic equation is a polynomial equation of degree two. It usually appears
in the standard form:
ax² + bx + c = 0
Here, a, b, and c are coefficients, and x is the variable. These equations are
common in algebra, physics, engineering, and real-world calculations.
How the Quadratic Formula Works?
The quadratic formula is: x = (−b ± √(b² − 4ac)) / 2a The solver uses this formula to calculate roots by:
- Identifying coefficients
- Calculating the discriminant
- Applying square roots
- Dividing by 2a
All steps are automated for accuracy.
Origin of Quadratic Equations
Quadratic equations date back to ancient civilizations like Babylonia and Egypt. Later, mathematicians such as Al-Khwarizmi refined algebraic methods. His work laid the foundation for solving polynomial equations systematically.
