Aug 26, 2019 · Consider x = 1 2. I) Since the statement is a ∀ -statement, it is sufficient to give one counterexample, to determine that this statement is false. Since x ∈ R we can take x = 1 2. Then ( 1 2) 2 = 1 4 ≥ 1 2 is false. II) For x ∈ Z this is true. Since x 2 ≥ 0 the statment is true for every negative integer, since then: Encontre as raízes da equação x² + 2x – 3 = 0. 1º passo: encontrar os valores dos coeficientes a, b e c. a = 1. b= 2. c ...
