Provide an appropriate response.A student is solving the equation s2 = 102 and has determined that s = 10. He or she has looked up the answer in the back of the book and finds that s = -10 is also a solution. The student feels that this is a misprint. How would you advise him or her?
What will be an ideal response?
102 = (-10)2 = s2 are both solutions.
