1. The problem is to find the solution and the cE (likely meaning critical point or equilibrium) of the given expression or equation. 2. Since the problem statement is incomplete, I will assume you want to solve a general equation or find the critical point of a function. 3. To solve an equation, we isolate the variable using algebraic operations. 4. To find the critical point (cE) of a function $f(x)$, we find where its derivative $f'(x)$ equals zero. 5. For example, if $f(x) = ax^2 + bx + c$, then $f'(x) = 2ax + b$. 6. Set $f'(x) = 0$ to find critical points: $$2ax + b = 0$$ 7. Solve for $x$: $$x = \cancel{\frac{-b}{2a}}$$ 8. This $x$ value is the critical point (cE). 9. Without a specific equation or function, this is the general method to find the solution and cE. 10. Please provide the exact equation or function for a precise solution.
