You can put this solution on YOUR website! Formulas are not said to be "rational" or "irrational".
Numbers are rational or irrational, but not formula.
`
Sometimes the quadratic formula gives a rational solution
and sometimes it gives an irrational solution.

You have not given the proper question. Check and see just
exactly how it was worded and then repost it stating it
that way.
======================================================
You are really stupid, it's not saying that the formula is irrational all the time it's saying to prove when this formula is irrational.
======================================================
Don't call me stupid. You're the one who asked the stupid
question
how do you prove that the quadratic formula is irrational?
What you should have asked is
How do you determine (not "prove") when (not "that")
the quadratic formula will give irrational solutions
(not "is irrational"?
The answer then would have been:
The solutions are irrational when the discriminant is not a perfect square.
