![]() ![]() In this section we will derive and use a formula to find the solution of a quadratic equation. ![]() Mathematicians look for patterns when they do things over and over in order to make their work easier. By the end of the exercise set, you may have been wondering ‘isn’t there an easier way to do this?’ The answer is ‘yes’. When we solved quadratic equations in the last section by completing the square, we took the same steps every time. However, the quadratic formula and the concepts involved can be implemented in various programming languages to solve quadratic equations.Solve Quadratic Equations Using the Quadratic Formula While the logic remains the same, the syntax may differ across programming languages. Can I use this program to solve quadratic equations in other programming languages? It does not handle other types of equations or non-quadratic expressions. This Python program assumes the input coefficients are real numbers and only solves quadratic equations. Are there any limitations to this Python program? Make sure to provide valid numerical inputs for the program to function correctly. If you enter non-numeric values for the coefficients, Python will raise a ValueError indicating that the input is invalid. What if I enter non-numeric values for the coefficients? Can Python handle complex roots in quadratic equations?īy using the cmath module, you can work with complex numbers and calculate the roots of quadratic equations with negative discriminates. You can solve a quadratic equation using a Python program.īy implementing the quadratic formula and considering different scenarios based on the discriminant, you can accurately calculate the roots. Print("The quadratic equation has one real root (repeated root):")įAQs About Python Program For Solving Quadratic Equation How can I solve a quadratic equation using Python? Print("The quadratic equation has two distinct real roots:") Roots = solve_quadratic_equation(a, b, c) Python Program For Solving Quadratic Equation import mathĪ = float(input("Enter the coefficient a: ")) You can try various combinations of coefficients a, b, and c and verify if the program produces the correct results. It’s important to test the program with different inputs to ensure its accuracy and reliability. To handle complex roots, we need to import the cmath module, which provides functions for working with complex numbers in Python.īy using cmath.sqrt(), we can calculate the square root of a negative number and obtain a complex result. Handling Complex Roots: Python Program For Solving Quadratic Equation Here’s the code: x1 = (-b + cmath.sqrt(D)) / (2*a) To handle this scenario, we can use the concept of complex numbers in Python. When D < 0, the quadratic equation has two complex roots.Ĭomplex roots consist of a real and an imaginary part. The Python code is as follows: x = -b / (2*a) In this case, the roots will be identical. When D = 0, the quadratic equation has one real root. The Python code for this case is as follows: x1 = (-b + math.sqrt(D)) / (2*a) ![]() We can use the quadratic formula to calculate these roots.
