ayudaa me sale mal ​

Answer 1

Explicación paso a paso:

FÓRMULA GENERAL

______

X= -b+- √b²-4ac

--------------------

2a

3x²-4x = -1

3x² -4x +1 = 0

A= +3

B= -4

C= +1

__________

X= -(-4)+- √(-4)²-4(3)(1)

-------------------------------

2(3)

_____

X=4+- ✓16-12

------------------

6

__

X=4+- ✓4

-------------

6

X= 4+-2

---------

6

X1= 4+2 6

--------- = ------- = 1

6 6

X2= 4-2 2

---------- = ------- = 0.333

COMPROBACIONES

3x²-4x = -1

3(1)²-4(1) = -1

3(1)-4 = -1

3-4 = -1

-1 = -1

3x²-4x = -1

3(0.333)²-4(0.333) = -1

3(0.110889)-1.332 = -1

0.332667-1.332 = -1

−0.999333 = -1

-1 = -1
