EQUAÇÕES INCOMPLETAS 2º GRAU - EXERCÍCIO RESOLVIDO
Autor: MARIA LUZIA | Publicado: 2016-08-31T17:26:00-07:00


Equações do tipo ax² + c = 0
Exemplos:
1. Resolver em lR a equação 2x²&nbsp; - 18 = 0.
Pelo método prático isolamos o 2x²&nbsp; no primeiro&nbsp; membro e levamos o -18 para o 2º membro com o sinal trocado.



Então as raízes são -3 e&nbsp;+ 3.
&nbsp;2. Resolver em lR a equação 4x²&nbsp; - 12 = 0 .
