Hello!
x² + 6x + 1 = 0 <=>
<=> x = -6±√6²-4×1×1/2×1 <=>
<=> x = -6±√36-4/2 <=>
<=> x = -6±√32/2 <=>
<=> x = -6±2²√2/2 <=>
<=> x = -6±4√2/2 <=>
<=> x = -6+4√2/2 <=>
and
<=> x = -6-4√2/2 <=>
<=> x = -3+2√2 <=>
and
<=> x = -3-2√2 <=>
x1 = -3-2√2 and x2 = -3+2√2
Good luck! :)

Answer:
(a) 5/6
Step-by-step explanation:
Positive numbers are greater than negative ones.
Fractions with the same denominator are greater if their numerator is greater.
All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...
5/6 > 1/6 > -1/6 > -5/6
The fraction with the greatest value is 5/6.
Step-by-step explanation:
an open (empty) point means the point itself is not included.
a closed (filled) point means the point itself is included.
the x values going from -3 (not included) to -1 (included) means
-3 < x <= -1
so, the second answer is correct.
