Answer:The roots are -3+√6 and -3-√6
Explanation:First, we would need to put the equation in standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
x² + 6x + 9 - 6 = 0
x² + 6x + 3 = 0
By comparison:
a = 1
b = 6
c = 3
Now, to get the roots, we will need to used the quadratic formula shown in the attached image.
By substitution, we would find that:
either x = -3 + √6
or x = -3 - √6
Hope this helps :)
