When you forget the quadratic formula but u have 1 minute left on the test

The link to the other attempts is privated

[WildeBob]

when you have one minute left in the test and you finally remember how to do that one question that you skipped.

Exercise/practice: _verify_ the quadratic formula by substituting into the polynomial and confirming an output of 0.

And you blackpenredpen'ed it too...

Bravo!

I can imagine you on a bus stop looking at the schedule and thinking "ok, my bus is arriving in 1 minute, what can i do in 1 minute? i know, let's proove the quadratic formula" :D

Back in high school I could never remember the quadratic formula so whenever I had a test that involved quadratic equations I quickly derived it as you did here (although not quite so quickly).

Integral of sqrt(1+(x^2+1)/x^2), thank you.
