Which of the following is not a polynomial ?a) ROOT 2 b) xc)1/x1 d) ROOT 3 x + 5 |
|
Answer» ( a ) Root 2 is a CONSTANT Polynomial as its DEGREE is zero ( b ) x is a linear polynomial having degree 1 ( as VARIABLE x have power equal to 1 which is a whole NUMBER ) ( c ) 1 / x = x ^ - 1 , Here power of variable x is - 1...which is not a whole number...( Degree of a ploynomial always a whole number but -1 is not a whole number...its an integer )...Thus 1 / x is not a ploynomial ( d )( Root 3 )x + 5 is a linear polynomial having degree 1 Thus Ans ( c ) |
