My bad. I apologize.

However, the question has a conflict because in the question we have x(x-6)(x+6)=0 but in the explanation, we have x(x-6)(x-8)

in the equation \(x(x-6)(x-8)=0\)

x=0
x=6
and
x=8

we know that \(x^2-36=0\)
\(x^2=36\)
\(x= \pm 6\)

The only value for x viable is 6

A is the answer
