Answer:
b=10
Step-by-step explanation:
you need to simplify it
10 is the sqrt of 100, 10*10=100.
Answer:
Required solution is
where A and B are constants.
Step-by-step explanation:
Given nonhomogenous differential equation is,
with 
To find another solution, consider
be such that,

Hence,
where A and B are constants.
Let



Hence,
where A and B are constants.
which is required solution.
