The equation has no real roots.  The curve does not touche or cross the x axis.
Refer to the attached plot.

but no solution is not part of the multiple choices...

agreene · Answer

As stated above, there are no real roots.
$$x=6\pm9i$$
are the complex roots.

anonymous · Answer

alright, not sure how that you got to the solution.

anonymous · Answer

x^2-12x+117
 solution :

deta = b²-4ac
deta= (-12)²-4*1*117
deta= -324
= 18i

x= 12+-18i/2 = 6+9i  or 6-9i

agreene · Answer

$$x^2-12 x+117 = 0$$
$$x^2-12 x = -117$$
$$x^2-12 x+36 = -81$$
$$(x-6)^2 = -81$$
$$x-6 = 9 i\;\;\text{or}\;\;\;x-6 = -9 i$$
$$x = 6+9 i\;\;\;\text{ or }\;\;\;\ x = -9 i+6$$
written another way...$x= 6\pm9i$
