Currently, I am enrolled in a Mathematics course for business, economics, life sciences, and social sciences. I believe this problem would be considered algebra though. Anyways, I am completely stuck on how to go about solving this problem. Can anyone assist me?

Solve the Equation for X

9^{6x-x^2}=9^{8 }Do I need to use the quadratic formula for the (6x-x^{2}) part? If so I did that and found the two numbers 0 , 3. But where would I go from here?
