+386 ok of the two expressions here which comes out as negative and which comes out positive:
(5 - (sqrt -59) ) / 6
(5+ (sqrt -59) ) / 6
And then are these supposed to work when entered in the calculator? :
+ sqrt ( (5+ (sqrt -59) ) / 6 )
and
- sqrt ( (5+ (sqrt -59) ) / 6 )
+129840 (5 - sqrt ( -59) ) / 6
(5+ sqrt (-59) ) / 6
The concept of "positive" and/or "negative" − in real number terms − has no meaning here, because both of these will be complex solutions......
+386 Thanks that's what I needed to know. I said "negative" but really just refered to i.
