"Yes, now I remember, a polynomial of 2nd degree, solved by d=b²-4ac where x' is (-b-squar. rac (d))/2a and x'' is (-b+squar. rac (d))/2a..." Arch remembered quickly (it was something he could only do once a year or so...)
"But, but, from who is this beautiful voice?"
He slowly turned back hoping to see a beautiful girl with blue hair sitting in kimono coming from the spirit world and named Botan but -
"Hey, Archie-Kun, you're not in Yû-Yû Hakushô! Wake up and react, cause the threat is still real! Look and hurry!" said the girl that Arch couldn't from now, but he could clearly the math teacher slowly arising with a vicious and fierce eye:
"You goddamn stubborn stupid student (3s
), I will crush and kill you not in a polynomial way, but in an exponential one! You'll suffer hell!"
(But how was the girl looking like? She certainly had japanese origins, while using the -kun form... To be continued)
