Here is the finished product for CS.
--------------------------------------------------
def CSquare(co1,co2,co3):
eq1=co1*x^2+co2*x+co3
eq3=eq1==0
eq2=factor(eq1)
eq4=(1/co1)*eq2
eq10=expand(eq4)
M1=maxima.args(eq10);L1=len(M1)
Cof1=maxima.args(eq10);Cof1a=Cof1[2];
val2=((1/2)*(maxima.coeff(eq10,x,1)))
Addon=maxima.ev(val2^2)
eq5=maxima.ev(val2^2)+M1[0]+M1[1]#this gets value from Maxima
eq6=factor(eq5);
eq7=-M1[2]+Addon;
Str1="This is added to both sides of the quad-- "
Soln=maxima.solve(eq1)
return eq3,eq2,eq10,eq6,Str1,eq7,Soln
-----------------------------------------------
The line that solve the problem was
Addon=maxima.ev(val2^2)
I now get a real number, that finishes the CS.
Willian, I need Maxima to write this function.
Here is some output.
---------------------------------------------
the call ---val1=CSquare(2,-1,-2);val1[0];val1[1];val1[2];val1[3];val1
[4],val1[5];val1[6]
2*x^2 - x - 2 == 0
2*(x^2 - x/2 - 1)
x^2 - x/2 - 1
(4*x-1)^2/16
('This is added to both sides of the quad-- ', 17/16)
[x=-(sqrt(17)-1)/4,x=(sqrt(17)+1)/4]
---------------------------------------------------------------------------------------------
the call--val1=CSquare(2,-1,-3);val1[0];val1[1];val1[2];val1[3];val1
[4],val1[5];val1[6]
2*x^2 - x - 3 == 0
2*(x - 3/2)*(x + 1)
x^2 - x/2 - 3/2
(4*x-1)^2/16
('This is added to both sides of the quad-- ', 25/16)
[x=3/2,x=-1]
-------------------------------------------------------------------------------------------
Now to get it work on my server. When I finish I will give the link.

Wolfram Alpha eat your hart out.
Still looking for help with pretty print output. (JSmath)
