Question

(2)-4*(1)*(-8) Delta

Answer 1

x² + 2x - 8 = 0
a = 1
b = 2
c = -8
Δ = b² - 4ac
Δ = 2² - 4 · 1 · (-8)
Δ = 4 - (-32)
Δ = 4 + 32
Δ = 36

Answer 2

(2)-4*(1)*(-8) Delta
pelo dados
a = 1
b = - 2
c = - 8
Δ = b² - 4ac     ( delta)
Δ = (-2)² - 4(1)(-8)
Δ = + 4 + 32
Δ = 36 -----------------------------> √Δ = 6    ( porque √36 = 6)
