Question

Fórmula de Báskara

6x²+x-1=0

Answer 1

6x² + x - 1 = 0
delta = 1 + 24 = 25 ou +_V25 = +-5 ****

x = ( -1 +-5)/12
x1 = -6/12 = - 1/2 ****
x2 = 4/12 = 1/3 ***

Answer 2

Δ = b² - 4 . a . c
x = (-b±√Δ)/2.a

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

Δ = 1² - 4 . 6 . (-1)
Δ = 1 + 24
Δ = 25

x = (-1±5)/12

x' = -6/12 = -1/2
x''= 4/12 = 1/3

Forte abraço!
