A polynomial with degree n has at most n unique roots. If a+(square root)b is a root or polynomial, then __________ is also a root. If a + bi is a root of a polynomial, then ______ is also a root.

OpenStudy (misty1212):

\[a-bi\] for the second one, but the first one is a copy and paste fail

OpenStudy (anonymous):

Opps let me fix that.

OpenStudy (misty1212):

that made it worse, too many question marks

OpenStudy (misty1212):

\[a-\sqrt{b}\]

OpenStudy (anonymous):

thank you. Could you help me on one more question?

OpenStudy (anonymous):

a. The number of positive roots (or zeros) is ____________________ the number of sign changes for the terms of a polynomial function _____. b. The number of negative roots (or zeros) is ____________________ the number of sign changes for the terms of a polynomial function _____. c. In each case, if the number of roots is less than the number of sign changes, then it differs by a multiple of _____.

OpenStudy (misty1212):

k mr x by whatever beans necessary

OpenStudy (anonymous):

lolol

OpenStudy (misty1212):

not sure how to answer the first one it is the number of change in signs of the coefficients, or counting down by twosq

OpenStudy (misty1212):

of \(f(x)\) for the second , it is the number of change in signs of \(f(-x)\) again counting down by 2's

OpenStudy (anonymous):

and the third one, is by multiples of 2's?

OpenStudy (misty1212):

yes

OpenStudy (aum):

a. The number of positive roots (or zeros) is * less than or equal to * the number of sign changes for the terms of a polynomial function * f(x) *

OpenStudy (anonymous):

alright, thanks guys. I'll probably be back soon lol
