## Homework Statement

solve the log x²-4x-5 on the base x-2.[/B]

## Homework Equations

I read a comment from someone that also saw the question that says:

making the equation equal to zero, the x values became approximately: 5.1623 and -1.1623

## The Attempt at a Solution

If it was x²-4x+4, that would be igual (x-2)² and the answer would be 2, but I have no idea the guy got these broken numbers. Making what equal to zero?

the x²-4x-5? Doesn't make sense.
