Question 1195008
<br>
Not clear....<br>
(1) Don't use "√" to indicate square roots -- we can't tell how much of the expression that follows is under the radical.
(2) Use more parentheses to make it absolutely clear what the expression is.  For example, I assume what follows the "/" should be (4x^2-1) -- that is, you are dividing by (4x^2-1), not dividing by 4x^2 and then subtracting 1.<br>
