I have multiple choice, and I know it's either "all real numbers except 10", or "all real numbers except 10 or -10". Will medal, please I need help!

understand it first-- which x values will make this equation have an error when i put it into a calculator? the only situation in this case is when you enter 1/0. So basically, all values of x but where x makes the equation invalid is the domain.

So "all real numbers except 10", right? Because 10-(-10) is 20
