Question

Calcule as raízes reais :
X2 - 1x=0

3x2-1x=0

6x2+ 1x =0

Answer 1

Calcule as raízes reais :


equação do 2º grau INCOMPLETA ( 2 raizes)
X2 - 1x=0

x² - 1x = 0
x(x - 1) = 0

x = 0
e
(x - 1) = 0
x - 1 = 0
x = + 1

assim
x' = 0
x'' = 1


3x2-1x=0

3x² -1x = 0
x(3x - 1) = 0

x = 0
e
(3x - 1) = 0
3x - 1 = 0
3x = + 1
x = 1/3

assim
x' = 0
x'' = 1/3


6x2+ 1x =0
6x² + 1x = 0
x(6x + 1) = 0

x = 0
e
(6x + 1) = 0
6x + 1 = 0
6x = - 1
x = - 1/6

assim
x' = 0
x'' = - 1/6
