![]() Please follow the Python tutorial series or the menu in the sidebar for the complete tutorial series.Īlso for examples in Python and practice please refer to Python Examples.Ĭomplete code samples are present on Github project.Īn investment in knowledge always pays the best interest. We have implemented and discussed both the important ways. In this article, we have learned how to solve any quadratic equation using Python program implementation. If you want to know more about cmath module, then you may click here. The functions in this module accept integers, floating-point numbers, or complex numbers as arguments. This module provides access to mathematical functions for complex numbers. We have used the cmath.sqrt(), cmath is actually a header file that contains different functions including the square root. The program directly tells the root since there is no particular condition we need to define. In the program, we have taken input from the user for all the three variables a, b, and c. The Quadratic Equation is of form ax2 + bx+ c Print("The Quadratic Equation is of form ax2 + bx+ c\n") #Python program to solve quadratic equation using math module Hence, we are now going to use one of the powerful modules which is cmath. Solving Quadratic Equation using the Complex math ModuleĪs we know, Python is filled with different libraries, functions, and modules. If you want to know more about the math module, you can click here.ģ. The function roots_of_equation has been defined to calculate the Discriminant value and to check the conditions after the Discriminant value has been calculated. In the above program, we have set the value of a, b, and c, instead, we can also take the value from the user. Print("Input correct Quadratic Equation") # If a is given 0, then Equation is incorrect # We can ask the user for value for a, b, c If D = 0, then the roots are real and equal.If D > 0, then the roots are real and distinct.The discriminant of the quadratic equation is D = b 2 – 4ac.The form ax 2 + bx + c = 0 will be followed, as this is the standard form.After entering the values, it will display the roots.Some of the important points which should be followed for solving the quadratic equations are: It will find the roots of the given quadratic equation. You can run this program, and it will prompt you to enter the coefficients (a), (b), and (c) of the quadratic equation. We will develop a python program to solve the quadratic equation. The result, including both roots, is printed to the console. Note that the cmath module is used to handle complex roots if the discriminant is negative. The roots are calculated using the quadratic formula. The discriminant (b 2 - 4ac) is calculated. The float() function is used to convert the input to floating-point numbers. Input() is used to get input from the user. Print("The roots of the quadratic equation are:") ![]() Next use conditional statements in the program. ![]() Use this formula X b2 4 a c to solve a quadratic equation. ![]() Use the following steps and write a program to find and display roots of quadratic equation in python: Import the math module. Root2 = (-b - cmath.sqrt(discriminant)) / (2*a) Python program to find the roots of an quadratic equation. Root1 = (-b + cmath.sqrt(discriminant)) / (2*a) Here's a Python program that takes the coefficients (a), (b), and (c) as input and calculates the roots of the quadratic equation: import cmath # Import the complex math module for handling complex rootsĪ = float(input("Enter the coefficient a: "))ī = float(input("Enter the coefficient b: "))Ĭ = float(input("Enter the coefficient c: ")) To solve a quadratic equation (ax 2 + bx + c = 0), you can use the quadratic formula: x = (-b ± √(b 2-4ac)) ÷ 2a ![]() Using it is just a matter of importing the module: Python > import math. Python Program To Solve Quadratic Equation Solving quadratic equations Simulating periodic functions, such as sound and light waves, using trigonometric functions Since the math module comes packaged with the Python release, you don’t have to install it separately. ![]()
