You can find the rate of change by taking it's derivative.
Hello!
To solve this, you are trying to convert one side to a quadratic equation and the other to just 0. Then, solve the equation.
----
First, move the /2 to the other side of the equation.
(a+1)/2 = 1/a
a+1 = 2/a
Next, multiply both sides by a.
a+1 = 2/a
And then subtract both sides by 2. This will get you to a quadratic equation.
Now, factor the equation. When we're factoring, we are looking for the form (a + b)(a + c), where b + c must equal 1 (the coefficient of a) and b*c must equal -2. In this case, b = 2, and c = -1.
Therefore:
(a + 2)(a - 1) = 0
To get the answer, recall that anything multiplied by 0 is equal to 0. Therefore, to get the left side to equal 0, either (a + 2) or (a - 1) must equal 0. To do this, a must either be -2 or 1.
Therefore, a = -2, or a = 1.

Check your work:
(-2 + 1)/2 = 1/-2
-1/2 = -1/2
(1 + 1)/2 = 1/1
2/2 = 1/1
1 = 1

Hope this helps!
Answer:
The number of palindromes is
when n is even and
when n is odd
Step-by-step explanation:
From the question we are told that
The length of the string is
Generally palindrome is evaluated by considering the first part of a string
When the the length of the string is an even number then
it means that the first part of the string is
Hence the number of bit strings of length n that are palindromes is evaluated as
But When the the length of the string is an odd number then
it means that the first part of the string is
Hence the number of bit strings of length n that are palindromes is evaluated as
Generally each bit could be either 0 or 1
Hence the number of palindromes is
when n is even and
when n is odd
