program to calculate and print roots of a quadratic equation: ax²+bx+c=0

-
import math
print ("For quadnatic equation, ax**2+ bx+ c.6, enter coefficlents below") 
a=int( input ( "Enter a :") )
b°=int( input ( "Enter b ;")) 
c= int( input ("Enter c :")) 
1f a==0:
     print (value of", a, ' should not be zero')
         print ("n Aborting !!!111")
 else:
      delta=b*b-4a*c
 if delta>0:
          root1=(-b+math.sart (delta)) / (2*a) 
         root2 =(-b-math. sqrt (delta))/ (2*a) 
       print ("Roots are REAL and UNEQUAL")
      print ("Root1=", root1, ", Root2=", root2) 
elif delta==0:
       root1=-b/ (2*a);
       print ("Roots are REAL and EQUAL")
       print ("Root1 ", root1, ", Root2 a", root1) 
else:
      print ("Roots are COMPLEX and IMAGINARY")


Output
 For quadratic equation, ax*2 + bx+ C- 0, enter coefficients below 
Enter a : 3
Enter b : 5
Enter c : 2
Roots are REAL and UNEQUAL Root1=-0.666666666667 , Root2=-1.0

program that reads two numbers and an arithmetic operator and displays the computed result.

-
num1=float(input("Enter first number:")) num2=float(input("Enter second number:")) op=input("Enter operator[ + - * / % ]:") result=0 If op == '+':         result=num1+num2 else op =='-':        result=num1-num2 else op =='*':        result=num1*num2 else op =='/':        result=num1/num2 else op =='%':        result=num1%num2 else:       print ("Invalid operator!!") print(num1,op,num2,'=',result) Output Enter first number:5 Enter second number:2 Enter operator[ + - * / % ]: * 5.0*2.0=10.0
