Use the quadratic formula to solve the equation. Give exact answers:
2x^2 1 = 6x.
The choices are:
a) 3 + square root(7)/2, 3  square root(7)/2
b) 3 + square root(11)/2, 3  square root(11)/2
c) 3 + square root(7)/2, 3  square root(7)/2
d) 3 + square root(11)/2, 3  square root(11)/2
I attempted this problem but got none of these answers! Could you please walk me through the problem and tell me which answer is correct? Thank you so much! :)

2 x^2  6 x  1 = 0
x = [ 6 +/ sqrt (36 + 8) ] / 4
x = [ 6 + / sqrt (44) ] / 4
x = [ 6 + / 2 sqrt (11) ] / 4
x = [ 3 +/ sqrt(11) ] / 2 so b
