x²-121=0
x²- 11²=0
(x +11)(x-11) = 0
x + 11 = 0 then x = -11
x - 11 = 0 then x = 11

Partial fractions are used in numerous aspects of everyday life, especially in fields requiring mathematical calculations. This includes engineering, calculus, computer science, signal processing, and electrical circuits. While we may not directly observe their use, their applications make many of our daily operations possible.
Explanation:
The concept of partial fractions is widely used in numerous aspects of our daily life, especially in fields that require mathematical calculations. Partial fractions make complex mathematical processes simpler and easier to solve.
For instance, in the field of engineering, partial fractions are used to simplify complex fractions in control system design, particularly in Laplace Transform. Moreover, it's also used in calculus to integrate rational functions.
In the realm of computer science, partial fractions can assist with algorithm efficiency when dealing with fractions or rational numbers. They are also used in signal processing and electrical circuits, which are a major part of our daily life as most electronics operate on these principles.
In everyday life, the use of partial fractions might not be directly observed but their applications in various fields make many of our daily life operations and technologies possible.

b. Event A is dependent on Event B.
c. Event B is dependent on Event A.
d. Events A and B are dependent on each other.
e. It is not possible to determine if the events are independent.
Answers
The true statement is that the (a) Event A is not dependent on Event B.
How to determine the true statement?
The equations are given as:
P(A | B) = 0.4
P(A) = 0.4
Two events A and B are independent if the following equations are true
P(A and B) = P(A) * P(B)
P(A | B) = P(A)
From the question, we have:
P(A | B) = P(A) = 0.4
This means that events A and B are not dependent
Hence, the true statement is (A)
