For the same polynomial above, use Descarte´s Rule of Signs to determine how many positive real roots are possible. Thank you very much. Answer by stanbon(57290)   (Show Source): You can put this solution on YOUR website!For P(x)=x^18+15^13+6^3-5x-1 with justification, list all possible rational zeros. For the same polynomial above, use Descarte´s Rule of Signs to determine how many positive real roots are possible. --- Possible Real Roots are p/q where p is a factor of -1 and q is a factor of 1 Possible Real Roots are +1 or -1 ------------------------------------ Decarte's Rule P(x) has one change of sign. # of positive real roots = # of changes of sign - {0 or 2 or 4 etc} ------------------------------------- Additional information can be found using Google to search for "DesCarte's Rule of Signs". ============================================= Cheers, Stan H. ===========
