the quadratic formula is marked as partially corrupted
I do not remember the quadratic formula. I do remember how to solve a quadratic by completing the square, though.

@anotherusername At university calculus we got a series of quadratic inequalities at some point which turned that into my preferred approach. No quadratic formula to misremember and you get the rest of the information you need for free.
