I can cut out the middle man for you.
You'll probably be learning this in a day or two. |

Oh hey...that. We learned that already. We just didn't call it that.
Code:
:Prompt A,B,C
:(b^2--4ac)->R
:If R>0:1->D
:If R=0:0->D
:If R<0:Then
:ClrHome
:Output(1,1, "No solutions...
:Stop
:End
:ClrHome
:If D=0:Output(1,1,"1 solution...
:If D=1:Output(1,1,"2 solutions...
:For(W,1,1000):End
:(-B+*The square root symbol*B^2-4ac)/2a->G
:(-B--*sqrt*B^2-4ac)/2a->H
:ClrHome
:Output(1,1,G
:Output(1,1,H
:For(W,1,1000):End
Hope this helps,

EDIT:Drat!! I've been beaten!
Download the file, then use Cemetech's SourceCoder to look at the source, then key it into your calc.

With some minor optimizations, such as the removing of end parenthesis and quotation marks. |

| What does the "solution/no solution" mean? Are you suppose to enter that in? |

| Yes, you type them in quotes. They are put on the screen using Output(. Anything in the third argument in quotes is displayed on the screen. |

| If you were graphing the function, then you would see that the curve never crosses the x-axis. Because of this, no set of sqares can be arranged to balance the equation. |

When you get into circles, you'll be dealing with two variables instead of one.
I made this a long time ago for that purpose, but be warned: it's a bit messy.
[font="courier new"]StoreGDB 1
FnOff
ClrHome
ClrDraw
GridOff
AxesOff
PlotsOff
Disp "ax²+by²+cx+dy+e
Input "a=",A
Input "b=",B
Input "c=",C
Input "d=",D
Input "e=",E
C/2:If A:Ans/A
Ans→X
D/2:If B:Ans/B
Text(0,0,"a(x+b)²+c(y+d)²+e
Text(‾1,56,72,"Swap
Text(‾1,16,0,"a=",A
Text(‾1,24,0,"b=",X
Text(‾1,32,0,"c=",B
Text(‾1,40,0,"d=",Ans
Text(‾1,48,0,"e=",A[font="times new roman"]π²+Be²+C[font="times new roman"]π+De+E-A([font="times new roman"]π+X)²-B(e+Ans)²
DelVar BRepeat 30=abs(A-75
Repeat Ans
getKey→A
End
If A=15
Then
If B
Then
DispGraph
Else
Output(8,13,"Swap
End
not(B→B
End
End
ClrHome
ClrDraw
RecallGDB 1
DelVar GDB1"
I'm sorry to say, it also doesn't factor the result...

for a TI 83 calculator
:lbl1
:disp "input X^2
:input a
disp "input x
:input b
:disp "input n
:input c
abs(b/2)->d
 ^2->z
:z+(-c)->e
:text(1,1,a,"x^2+",b,"x+",z,"=",e
text(7,1,"sqrt(x-",d,")^2=sqrt",e
:if e<1:then
:e*(-1)->e:sqrt(e)->e
:text(14,1"x-",d,"=+",e,"i
:text(21,1)"x-",d,"=-",e,"i
:pause
:goto1
:end
:if e>1:then
:sqrt(e)->e
:text(14,1,"x-",d,"=",e
:pause
:goto1
