Question

Resolva a equação do 2* grau X²-6×+8=0

Answer 1

Resolva a equação do 2* grau

x² - 6x + 8 = 0

os coeficientes

a = 1, b = -6, c = 8

delta

d = 36 - 32 = 4

as raízes

x1 = (6 + 2)/2 = 4

x2 = (6 - 2)/2 = 2

o vértice

Vx = -b/2a = 6/2 = 3

Vy = -d/4a = -4/4 = -1  

Answer 2

x1 = 2

x2= 4
