Description
For this week, consider these exercises:
Section Number | Discussion Problems |
9.1 | 2, 4, 6, 10, 16 |
9.2 | 4, 6, 14, 22 |
9.3 | 16, 18, 20, 24, 28, 32, 40, 42, 54, 56 |
9.4 | 8, 16, 20, 26, 32, 38, 40 |
9.5 | 12, 26, 32 |
9.6 | 4, 8, 14, 30, 38, 42, 46 |
9.7 | 4, 8, 10, 12, 16, 22, 26 |
To participate, choose ONE of the problems listed in the Discussion Problems Column that has not already been chosen by a classmate:
1. Click the "Start a New Thread" button below the instructions to post your solution.
2. Write the section and problem number into the subject line. Example: Section 1.5 #28.
(Using this format will list the problems in order so that you can see if a problem has already been selected by a classmate.)
3. Be sure to write out the directions for the problem and the original statement of the problem then show work or an explanation with your solution; generally speaking, do not just state your answer.
Explanation & Answer
Hi,Attached is the answer. Let me know in case of any explanations or revisions.

π2 β 16π β 52 = 0
We have to convert left side polynomial into perfect square.
Comparing it with ππ₯ 2 + ππ₯ + π
We get
π = 1, π = β16, π = β52
Since a = 1, we can go with next step of writing polynomial as
π2 β 16π = 52
1
Adding both sides by (2 π)
2
So adding 64 on both sides we get
π2 β 16π + 64 = 52 + 64
So we get
π2 β 8π β 8π + 64 = 116
So we get
π(π β 8) β 8(π οΏ½...
