Can we enter a program such that it solves quadratic equations?

To solve ax^2+bx+c=0 use this 20 line program:
[-] [RDN] [x<>y] [/] 2
[/] [CHS] [ENTER] [x] [g][LSTx]
[x<>y] [RDN] [RDN] [/] [-]
[g][SQRT] [-] [x<>y] [g][LSTx] [+]
To use it:
a [ENTER] b [ENTER] c [ENTER] 0 [R/S]
eg:
1[ENTER] [CHS][ENTER][ENTER] 0 [R/S], see 1.618, then [RDN] shows -.618, the other root, of x^2-x-1=0.
