Solve by adding 16 to both sides of the equation yielding: x^2 = 16. Then take the square root of both sides (remembering that taking the square root gives us a positive and a negative answer), giving us ...

Okay so the first thing we can identify is that it is a quadratic, hence the x² at the beginning. From this we can now start to answer the question. To calculate the minimum po...
