What is the coolest way of programming the quadratic formula in J? We are
finding the roots of polynomial c + x*(b + x*a) without using p. . I offer
roots
3 : 0
'a b c' =. y
q =. %: (b^2) - 4*a*c
(2*a) %~ (-b) + q,-q
)
roots 1 3 2
_1 _2
roots 1 0 1
0j1 0j_1
roots 1 _2 1
1 1
partly as problem definition. I am looking for cool roots verbs!
