Question

equação do segundo grau 6 x elevado a 2 + 4x - 2 = 0

Answer 1

6x² + 4x - 2 = 0 √Δ = b² - 4 ac √Δ = (4)² - 4*(6)*(-2) √Δ = 16 - (24)*(-2) √Δ = 16 + 48 √Δ = 64 √Δ = 8 x = -b +/- √Δ / 2*a x = -4 +/- √Δ / 2*6 x = -4 +/- 8 / 12 x' = -4 + 8 / 12 x' = +4/12 x'= 1/3 x'' = -4 -8/12 x'' = -12/12 x'' = -1

Answer 2

6x² + 4x - 2 = 0

√Δ = b² - 4 ac
√Δ = (4)² - 4*(6)*(-2)
√Δ = 16 - (24)*(-2)
√Δ = 16 + 48
√Δ = 64
√Δ = 8

x = -b +/- √Δ / 2*a
x = -4 +/- √Δ / 2*6
x = -4 +/- 8 / 12

x' = -4 + 8 / 12
x' = +4/12
x'= 1/3

x'' = -4 -8/12
x'' = -12/12
x'' = -1

Um abraço!
