Answer:First choice
Step-by-step explanation:To get the roots of the function, we will use the quadratic formula attached in the image.
The given equation is:
x² + 10x - 6 = 0
We have:
a = 1
b = 10
c = -6
Substitute in the formula, we will find that:
either x =

= -5 + √31
or x =

= -5 - √31
Hope this helps :)
