Step-by-step explanation:

so the complimentary solution is

solving for particular solution we get

to find the values of constants a,b we put values in main equation and

as g(x)=sin x
so above equation yields us

so writing the solution

using IC's to get the values for 

solving for upper range

Answer:
-6
Step-by-step explanation:
First multiply -6 and 4 which is -24.
Then add 20 and -24 which is -4
Then subtract -4 and -2
Which is -6.
