Answer:
The given power series
is a solution of the differential equation (1+x^2)y' + 2xy = 0
Step-by-step explanation:
This is a very trivial exercise, follow the steps below for the solution:
Step 1: Since n = 0, 1, 2, 3, 4, ........, Substitute the values of n into equation (1) below.
.....................(1)

Step 2: Find the derivative of y, i.e. y'

Step 3: Substitute y and y' into equation (2) below:

(Verified)
Since the LHS = RHS = 0, the given power series
is a solution of the differential equation (1+x^2)y' + 2xy = 0
Answer:
I think it's 34
Step-by-step explanation:
cuz you add 11 and 12 frequency
-|2x+3| > 2 and <span>-|2x+3| > - 2
</span>-2x+3 > 2
-2x > 2 - 3
-2x > -1
-2x / -2 > -1 / -2
x < 1/ 2
-|2x+3| > - 2
x < 5/2
