(6) Let PW) be a polynomiel with complex coefticieabs, and Let 1eC be a root of Pla). Then the conjugate a is also a root of PlW. True. The roobs of Pu) always come in conjugate peirs. True. This is also why the conjugate of an eigenvalue (nan)-metrix A over & is itself an eigenvelue of A. O False. A counteiexample is Ehe yolynominl Pa)=x-1, which has only one rook, namely 1. In porticular, T camnot be a in root of PlW).
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
