1. The problem is to solve the given questions (please specify the exact questions for detailed help). 2. Generally, for algebra problems, we use formulas such as the quadratic formula $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$ for quadratic equations, or rules like distributive property, factoring, and simplification. 3. To solve any algebraic problem, first identify the type of equation or expression. 4. Then apply the appropriate formula or method step-by-step, showing all intermediate calculations. 5. Simplify the expressions carefully, and check your answers by substitution if possible. Please provide the specific questions so I can give detailed step-by-step solutions.
