Question

como é que faz a conta de bhaskara

Answer 1

∆ = b² – 4 * a * c
∆ = (–2)² – 4 * 1 * (–3)
∆ = 4 + 12
∆ = 16



x = – b ± √∆
2∙a

x = –(– 2) ± √16
2∙1

x = 2 ± 4
2

x' = 2 + 4
----------------
2

x' = 6 / 2

x' = 3



x'' = 2 – 4
---------------
2

x'' = -2/2

x'' = -1

Answer 2

Δ= b² - 4.a.c

x= -b +/- √Δ ÷ 2a
