Provide an appropriate response.Consider the following: 
+ 3 = 5 
= 2 (
)2 = 22 x = 4What would have happened if the radical had not been isolated before the principle of squaring was used? Could the equation still have been solved? Why or why not?
What will be an ideal response?
A radical term would have remained after the principle of squaring was used. The equation could still have been solved if the radical were isolated at this point and the principle of squaring was used again. This might introduce an extraneous root.
