3 x² + 2x-1=0 utilizando formula cuadratica
​

Answer 1

Respuesta:

x1 = 7/2

X2 = 9/2

Explicación paso a paso:

3 x² + 2x-1=0

a = 3

b = 2

c = -1

x = -b +-√b^2 -4*a*c

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

2*a

x = -2+-√2^2 -4*3*(-1)

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

2*2

x = - 2+-√4+12

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

4

x = -2+- 16

---------

4

x1 = -2+16/4=14/4=7/2

X2 = -2-16/4=-18/4=9/2
