Question

as soluçoes da equaçao 2xao quadrado - 3x + 1 = 0, sao

Answer 1

2x² - 3x + 1 = 0

Δ = b² - 4 . a . c

Δ = (-3)² - 4 . 2 . 1

Δ = 1

x = (-b +- √Δ) / 2a

x = (-(-3) +- √1) / (2 . 2)

x = (3 +- 1) / 4

x' = (3 + 1) / 4

x' = 4/4

x' = 1

x'' = (3 - 1)/4

x'' = 2/4

x'' = 1/2

Resposta: S = {1 ; 1/2}
