Answer 1

ABC :

x² + 6x + 8 = 0

A = 1

B = 6

C = 8

MAKA :

= -6 ± √6² - 4(1(8)/2(1)

= -6 ± √(6(6) - 4(8)/2

= -6 ± √36 - 32/2

= -6 ± √4/2

= -6 ± 2/2

X1 = -6 + 2/2 = -4/2 = -2

X2 = -6 - 2/2 = -8/2 = -4

HP = {-2,-4}

FAKTORISASI :

x² + 6x + 8 = 0

(x + 4)(x + 2) = 0

(x + 4) = 0 V (x + 2) = 0

x = -4 V x = -2

HP = {-2,-4}
