Question

((t^2/sqrt t^2+1)-sqrt t^2+1))/t^2

Is the LCD to multiply by sqrt t^2+1?????

Please help!

Answer 1

Hard to say; the parentheses are unbalanced. It could be

t^2/√(t^2+1) - √(t^2+1)
-------------------------
t^2

Then you could proceed like this

t^2 - (t^2+1)
------------------
t^2 √(t^2+1)
.

.
-1
---------------
t^2 √(t^2+1)
