Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.

The rank order of the activities to be completed are:
- Work on ongoing project
- Investigate customer issue
- Complete Online Training
- Attend team meeting
<h3>How to order the events?</h3>
From the complete question (see attachment) the events must be ordered based on their priorities, followed by the time and then impact.
Using the above highlight, the events with the top priorities are:
Events 1 and 2
The events with the most number of hours are:
Events 1 and 2
Event 4 has more priority than event 3.
So, we have the following order
1, 2, 4 and 3
