Please help me find what wrong with this Solve 3x2 + 6x + 1 = 0

Step 1) a = 3, b = 6, c = 1

Step 2) x=6±62−4(3)(1)√2(3)

Step 3) x=6±36−12√6

Step 4) x=6±24√6

Step 5) x=1±6√3

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
