Question

Equação de 2° grau a =1,b=0ec=-9

Answer 1

Resposta:

Olá,

→ S = (3 ; -3)

a = 1

b = 0

c = -9

x² - 9 = 0

x = (-b ± √b² - 4ac)/2a

x = (-0 ± √0² - 4 × 1 × (-9))/2 × 1

x = (0 ± √0 - 4 × 1 × (-9))/2 × 1

x = (0 ± √0 - 4 × (-9))/2 × 1

x = (0 ± √0 - (-36))/2 × 1

x = (0 ± √36)/2 × 1

x = (0 ± 6)/2 × 1

x = ±6/2 × 1

x = ±6/2

x' = 6/2

x' = 3

x" = -6/2

x" = -3
