forme equations second degree
ax2+bx+c
forme canonique:
f(x)=a(x-alpha)2+beta
a+ corbe tournée vers le haut x admet alors un min en x=alpha 
a- courbe tourne vers le bas  x admet alors un max en x=alpha 
f(alpha)=beta
alpha=-b/2a
delta=B2-4ac
si delta +alors
x1=-b-sqrt(delta)/2a
x2=-b+sqrt(delta)/2a 
factrotisation:ax2+bx+c=a(x-x1)(x-x2)
si delta - alors la fonction n'admetpas de racines 
si delta=0 alors la fonction a une racines double 
factorisation: ax2+bx+c=a(x-x0)2
