ide o standardnu kvadraticku rovnicu ktora ma tvar ax^{2}+bx+c=0

v nasom pripade:
a=1
b= 2
c= 2^-4 alebo 1/16

vypocitame diskriminant D=b^{2}-4ac.

a podla vysledku D urcime ake riesenia.

D = 0, rovnica ma jeden dvojnasobny koren, x= -b/2a

D > 0, rovnica ma dva korene x(1,2)= (-b +- sqrt(D)) / 2a

D < 0,rovnica nema riesenie v obore realnych cisel
