Algebra Question: Can't remember how to to these

[Sahamamama]

If x > 2, then x(squared) - x - 6/x(squared) - 4 =

How do I solve this? I'd ask my husband, but he's asleep. TIA!

Parenthesis first, then Exponents, then Multiply/Divide (from left to right), then Add/Subtract from left to right.

Depends on which you mean.

If you mean:

x²-x-6
------
x²-4

Then what you need to do is factor both top and bottom. I think you'll easily see the answer once you do that :)

BTW, if that was what you mean, you may find it easier to either type it out on different lines or put parentheses around each section of the problem as your problem looks like 6 is divided by x²-4. If you DID mean that, then look at cillakat's reply :)

If it is (x^2-x-6)/(x^2-4) then...

since x>2, you don't need to worry about the undefined points at x=2, nor x=-2.

Yes, exactly that. Can you believe it, I am trying to reteach myself Algebra I, duh. Thanks, everyone! :001_smile:
