1. The problem asks whether the left-hand side (LHS) of an equation or expression is positive or negative at $x=0$. 2. To determine this, we need the explicit form of the LHS function or expression. 3. Evaluate the LHS by substituting $x=0$ into the expression. 4. If the result is greater than zero, the LHS is positive at $x=0$. 5. If the result is less than zero, the LHS is negative at $x=0$. 6. If the result equals zero, the LHS is neither positive nor negative at $x=0$. Since the specific expression is not provided, we cannot compute the exact value at $x=0$. Please provide the expression for the LHS to determine its sign at $x=0$.
