Solve the complex fraction
((t^2/sqrt t^2+1)-sqrt t^2+1))/t^2
Is the LCD to multiply by sqrt t^2+1?????
Please help!
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)
