Equacao 2 Grau

Lembrando os velhos tempos, escrevi o programa que resolve equacoes do segundo grau no Microsoft Small Basic, vamos ao codigo-fonte :
' Programa Equacao do Segundo Grau
' Codigo para resolucao de equacoes do segundo grau
' para Microsoft Small Basic
valorA = 0
valorB = 0
valorC = 0
delta = 0
raiz = 0
x1 = 0
x2 = 0

TextWindow.WriteLine("EQUACAO 2 GRAU")
TextWindow.Write("Informe o valor A : ")
valorA = TextWindow.ReadNumber()
TextWindow.Write("Informe o valor B : ")
valorB = TextWindow.ReadNumber()
TextWindow.Write("Informe o valor C : ")
valorC = TextWindow.ReadNumber()

'calcular delta

'se o valor de delta for positivo ou igual a zero
If (delta>=0) Then
raiz = Math.SquareRoot(delta)
x1 = (raiz-valorB)/(2*valorA)
x2 = ((raiz-valorB)/(2*valorA))*(-1)
TextWindow.WriteLine("Valor X1 = " + x1)
TextWindow.WriteLine("Valor X2 = " + x2)
TextWindow.WriteLine("Delta negativo!")
TextWindow.WriteLine("Nao existe solucao dentro do conjunto dos numeros reais.")
TextWindow.WriteLine("Implemento isso outra hora :-)")

Detalhe que este foi o primeiro problema que resolvi quebrando a cabeca na epoca do BASIC. Ate a proxima :-)

  10. Making use of a v2 electronic cigarette will assist to flush toxins from normal cigarettes from
    the body and increase wellness. E cigarettes are designed to look and feel like
    genuine cigarette. You are by no means alone when you have your
    little "buddy" with you, some sayâ€"a comfort that comes as quickly as a flame can be lit. When smokers start off to cut down on cigarettes, they commence to go into withdrawal, which causes a range of unpleasant symptoms including headache, fatigue, irritability and cravings. You can also appear up other brands that are just as tempting as the subsequent when it comes to going the green way.
