1.     (a)  Given the following equation,      use synthetic division to test the following 3 pts and show which one is a root.   Must show synthetic division for all 3 of the following test pts.   Test these 3 possible root pts also called possible zeros

using synthetic division.   (x,y) =  (-1, 0) ;   (-3, 0)   ;   (2, 0).

 

 

2.      Using the rational root theorem, list the possible zeros:

 

Using p/q list all the possible zeros of the following equation     3x^2 – 7 = 0.

Hint:  there are 8 correct answers.

Suggested format for answer:  

List factors of p:

List factors of q:

List possible zeros:    +/- p/q

 

 

3.     Simplify the expression (x^(4)+4x^(2)-6x-24)-:(x+4) using synthetic division. Show your work just an answer without showing the synthetic division will get a zero grade.   After doing the synthetic division, which gives you just coefficients.  Convert the coefficient quotient answer, into a polynomial with variable x and the correct exponent powers in it.   Convert your coefficient answer into a polynomial.

Hint:  remember to fill in any missing degree terms in your dividend with coefficients that are zero to represent missing place holders.

No equation is shown in 1    and no expression is shown in 3.....

Can you do number three again, forgot to put the equation for it in.

3.     (x^(4)+4x^(2)-6x-24)-(x+4)

 

Simplify  and we have     x^4 -4x^2  -7x - 28

 

WolframAlpha  shows that we have no rational roots for this  : 

 

https://www.wolframalpha.com/input/?i=%28x%5E4%2B4x%5E2-+6x+-+24%29+-+%28x%2B4%29

 

Are you sure that you have the correct function  ????
