3X²-X=0
X(3X-1)=0
X=0
OU
3X-1=0
ENTÃO:
3X-1=0
3X=1
X=1/3
X={0 , 1/3}
UM ABRAÇO!!!

Baskaras:
-b ± √(b² -4ac)
x = -------------------
2a
No caso:
a = parte numerica do x², o seja 3
b = parte numerica do x, o seja -1
c = parte numerica sem x, o seja 0
x = [1 ± √(1 - 4*3*0)] / 6
x = (1 ± √1) / 6
x = (1 ± 1) / 6
x1 = 2/6 = 1/3
x2 = 0/6 = 0
As soluçoes sao dois: 1/3 e 0

3X²-X=0 ENTAO X(3X-1)=0 DAI PODEMOS DIZER QUE
X=0 OU 3X-1=0
X=1/3 LOGO, S={0, 1/3}

3x² - x = 0
x(3x - 1) = 0
x = 0
3x - 1 = 0
x = 1/3
S={0, 1/3}

3x²-x = 0
x(3x - 1) = 0
x = 0
3x = 1
x = 1/3
Solução = {(0; 1/3)}

3x² - x = 0
x (3x - 1) = 0
x' = 0
3x - 1 = 0
x'' = 1/3

3x²-x = 0
x*(3x - 1) = 0
ou x = 0
3x - 1 = 0
3x = 1
x = 1/3
ou x = 1/3, anulam a equacao.
resposta: x=0 ou x=1/3
