Question

list the possiblities for the nature of the roots (positive real, nexative real, and imaginary) for the equation p(x)=0
p(x)=x^5+x^4-3x^2-4x+6

Answer 1

\[\pm1,\pm2,\pm3,\pm6\]

Answer 2

the factors of the constant divided by the leading coefficient

Answer 3

atlkeast 2 real roots

Answer 4

wait you use the descartes rule of signs

Answer 5

how do uyou find the imaginery number

Answer 6

1 negative real, 4 imaginary

Answer 7

im confused

Answer 8

hopefully this is the one you were asking me about... first i would look at teh highest power, (5) which is the number of roots, with this question you have two sign changes, so theres positive negative possibilities and im going to assume there are no imaginary numbers because there are no 'i's' until mrjoselson explains otherwise.
