Answer 1

Answer:

The number of byes are decided by subtracting the number of teams from the next higher number which is in power of two's. Formula for calculating number of matches=n-1,where n is the total number of teams participating in the tournament.Formula to calculate the Bye is:

(a) Subtract from next power of two (b) Addition from next power of two

(c) As per number of teams (d) None of theseshiirtmaniaFind all zeroes of polynomial x* +X-34X°. 4x+120, if two of its zeroes are 2 and 2shiirtmaniaFind all zeroes of polynomial x* +X-34X°. 4x+120, if two of its zeroes are 2 and 2x2 - 4 is a factor of f(x). Now, we divide x4 + x3 − 34x2 − 4x + 120 by g(x) = x2 - 4 to find the other zeros of f(x). Hence, the zeros of the given polynomial are -2, +2, -6 and 5.
