3x^2 - 7x - 2 = 0
a = 3, b = -7, c = -2

x = (-b (+-) sqrt b^2 - 4ac) / 2a
x = -(-7) (+-) sqrt -7^2 - 4(3)(-2)) / 2(3)
x = (7 (+-) sqrt (49 + 24) / 6
x = (7 (+-) sqrt 73) / 6...answer is B
Hey there, Lets solve this problem together. 

[tex]3x^2 - 7x - 2 = 0 [/tex]

Let the variables 

a = 3,
b = -7,
c = -2

[tex]x = (-b (+-) sqrt b^2 - 4ac) / 2a x = -(-7) (+-) sqrt -7^2 - 4(3)(-2)) / 2(3) x = (7 (+-) sqrt (49 + 24) / 6 x = (7 (+-) sqrt 73) / 6[/tex]
