Step-by-step explanation:
Part 41) we have

step 1
Find the first solution (case positive)




step 2
Find the second solution (case negative)





therefore
The negative case was resolved incorrectly
The solutions are 3 and 1
Part 42) we have
step 1
Find the first solution (case positive)



<em>Verify</em>
For n=-3
substitute
------> is not true
therefore
-------> is not a solution
step 2
Find the second solution (case negative)





therefore
The solution is 2
