I have been using a technique that's almost identical to this for years, based simply on observing that the roots are symmetric around the min/maximum: differentiate, set to zero, then difference of squares.
This cannot be an unrecorded technique can it?
- mkl 7y agoNo, it's basically what the quadratic formula does. (Well, all methods solve the same equation and get the same roots, so they have to be equivalent.)
