Na podstawie wzoru funkji kwadratowej f w postaci iloczynowej podaj miejsce zerowe funkcj:
a) f(x) = ₋¼(x-√2) (x+3)
b) f(x) = ⅔ (x+8) (x-1)
c) f(x) = -⅖x (x-6)
d) f(x) = 2 (x-1 +√3)
e) f(x) = 1/5 (x+1+ √2) (x+3- √2)

a) f(x) = ₋¼(x-√2) (x+3)
x=√2 x=-3)
b) f(x) = ⅔ (x+8) (x-1)
x=-8 x=1
c) f(x) = -⅖x (x-6)
x=0 x=6
d) f(x) = 2 (x-1 +√3)
x=1 -√3
e) f(x) = 1/5 (x+1+ √2) (x+3- √2)
x=-1- √2 x=-3+ √2
