Answer:

Step-by-step explanation:
The given quadratic equation is:

Comparing it with the standard form of Quadratic Equation
, we get:
a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69
I think it’s 468 I might be wrong
In x th month, members =
. Option D.
Step-by-step explanation:
Given,
Initially number of members = 3
Every month each member brought 1 new member.
To find the number of members after x months.
<u>Solution:</u>
In 1st month, members = 3
In 2nd month, members = 3×3 = 9 = 3²
In 3rd month, members = 9×9 = 81 = 
In 4th month, members = 81×81 = 81 = 6561 = 
Hence,
In x th month, members =
