can you please explain how to get the result for number 8 please. I am so lost
![PROBLEMS: Section 3.3
For Problems 1-10, a differential equation and one solution are given. Use
d'Alembert's reduction of order method to find a second linearly
independent solution. What is the general solution of the differential
equation?
Differential equation
1. y" - y = 0
2. y" + y =0
3. " - 4y' + 4y = 0
4. " +y' = 0
5. " + y = 0
6. xy" - 2(x + 1)y' + 4y = 0
7." - 6y = 0
8. x²y" - xy + y = 0
9. (²+1)y" - 2xy' + 2y = 0
Solution
Y₁(x) = et
y₁(x) = sin x
y₁(x) = ²x
y₁(x) = 1
y₁(x) = 1
y₁(x) = ²x
y₁(x) = x³
y₁(x) = x
y₁(x) = x](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa8f598d6-fb79-49b9-b541-8d3a3f2f5721%2F5558df0f-e13a-4ced-825b-551295b5d0ff%2F6vcgpptr_processed.png&w=3840&q=75)
