Enter the coefficients a,b,c of X in a quadratic equation

:1

    

-1                                                         

-2                                         

                                     

First root is:2                                                                

Second root is:-1                                                           

Algorithm:

Read A,B,C
  
Set D = B2- 4*A*C                  
  
If D > 0, then :
 



a)     
Set E = - B + sqrt (D)/2*A 



And F= - B - sqrt (D)/2*A 



b)    
Write: E, F



       Else 



               Write: ‘NO REAL SOLUTION ‘
