Zamień funkcję kwadratową na postać kanoniczną
y=x^{2} -10x+27
postac kanoniczna : y=a(x-p)^2 + qmasz dane : a=1, b=-10, c =27mozesz wiec obliczyc delte : b^2 - 4ac
delta = 100 - 108 = -8
p = -b:2a = 10:2 = 5q= -delta:4a = 8:4 = 2postac kanoniczna : y=(x-5)^2 + 2
y=x²-10x+27
a=1
b=-10
c=27
x(w)=-b/2a
x(w)=-(-10)/2=5
y(w)=f(5)
y(w)=5²-10·5+27=25-50+27=2
