Final answer:
To find all possible solutions to an equation or system of equations, step-by-step solutions must be followed. The solutions can include one solution, multiple solutions, no solution, or complex solutions. It is important to carefully analyze the given equations and apply appropriate solving techniques.
Step-by-step explanation:
- Determine the equation or system of equations you need to solve.
- Check if the equation or system of equations has one solution, multiple solutions, no solution, or complex solutions.
- Apply appropriate solving techniques to find the solutions.
- If using a calculator, utilize relevant functions or tools to solve the equations.
Given equation: x^2 + 4 = 0
The equation is quadratic and contains an unknown squared, so there will be two solutions. In this case, there are no real solutions because the discriminant (b^2 - 4ac) is negative. Therefore, the answer is c) No solution.
Remember to carefully analyze the equations and determine the appropriate solution based on the given information.
