Help me with my program...?

I want the output like this:





Example output:


Enter coefficient a: 4


Enter coefficient b: 4


Enter coefficient c: 1


Quadratic _expression: 4x2 + 4x + 1


The roots are real: x1 = -0.5 ; x2 = -0.5


It is a perfect square.


Evaluating the _expression:


Enter x: 2


Result : 25





Enter coefficient a: 2


Enter coefficient b: 5


Enter coefficient c: 10


Quadratic _expression: 2x2 + 5x + 10


The roots are imaginary.


Evaluating the _expression:


Enter x: 1


Result : 17





Enter coefficient a: 1


Enter coefficient b: 0


Enter coefficient c: -1


Quadratic _expression: x2 + 0x + -1


The roots are real. x1 = -1 ; x = 1


It is not a perfect square.


Evaluating the _expression:


Enter x: 5


Result : 24





I can't do it like the output above...pls edit

Help me with my program...?
i gt the program to run as what your output is. Pls email for the solution. i cant post the coding here, i think some part of the codes is missing. thanks.
