Question

3 x ao quadrado menos 4x + 1 = 0

Answer 1

3x² - 4x + 1 = 0

x=4 +- √16 - 12
   -------------------
            6

x = 4 +- √4
    -------------
          6

x' = 4 + 2
      --------
          6

x' = 1

x" = 4 - 2
      --------
         6

x" = 1/3

Answer 2

A=1
B=4
C=1

1* DELTA:
DELTA= 4^2 -4.1.1
DELTA = 16-4
DELTA = 12

2*BASCARA:

X =
$\frac{ - 4 + - \sqrt{12} }{2}$
X=-4+3raizde2 /2
X=7raizde2 /2
