Python | Finding Solutions of a Polynomial Equation
Given a quadratic equation, the task is to find the possible solutions to it.
Input : enter the coef of x2 : 1 enter the coef of x : 2 enter the constant : 1 Output : the value for x is -1.0 Input : enter the coef of x2 : 2 enter the coef of x : 3 enter the constant : 2 Output : x1 = -3+5.656854249492381i/4 and x2 = -3-5.656854249492381i/4
Start. Prompt the values for a, b, c. Compute i = b**2-4*a*c If i get negative value g=square root(-i) Else h = sqrt(i) Compute e = -b+h/(2*a) Compute f = -b-h/(2*a) If condition e==f then Print e Else Print e and f If i is negative then Print -b+g/(2*a) and -b-g/(2*a) stop
Below is the Python implementation of the above mentioned task.
the values for x is -1.0
First, this program will get three inputs from the user. The values are the coefficient of , coefficient of and constant. Then it performs the formula
For complex the value of gets negative. Rooting negative values will throw a value error. In this case, turn the result of and then root it. Don’t forget to include at last.
