multi-part polynomial question.
Ok, so I have a question involving a Polynomial and finding its roots.
A. How many possible positive roots are there?
B. How many possible negative roots are there?
C. What are the possible rational roots?
D. Using synthetic substitution, which of the possible rational roots is actually a root of the equation?
(Answer:I'm not sure on how to show synthetic division/substitution using [tex] tags, but my answer is that 1 is the actual real root of the equation.)
E. Use the quadratic formula to find the irrational roots of the resultant depressed equation.
(Answer: I'm a little fuzzy here.....the depressed equation I got was: . My question is, did I get the correct equation?
If I did then I am certain that I can do the rest, it is just the quadratic equation--one of the few things I actually understand.)
