Which of the following is not a polynomial ? a) ROOT 2 b) x c)1/x 1 d) ROOT 3 x + 5 |

Answer» ) 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 ) |
