The image contains only the mathematical equation to be solved or analyzed. There is no question stem asking what to do with the equation (e.g., solve for x, find the domain, etc.), no options, and no other text like instructions or explanations. The request asks to extract "all content related to the question(s)". Since there's no explicit question asked *about* the equation, I will treat the equation itself as the primary content to be extracted.
