Hello there,
Today in class, my teacher said the following:
The interval over which the implicit solutioncan be found by considering the quadratic formula
. The interval of which
can be defined is precisely the interval of which the determinant
is real (non-complex).
What I'm not sure about is how can we treat the implicit solution as a quadratic, when. Ordinarily, quadratic applies to the form
where here
and naturally,
. But since
, my sense is that quadratic can't be used.
Thanks for the help.
