Question

State which of the following are polynomials and which are not? Give reasons.(i) 2x³ (ii) 1/(x-1) (iii) 4z² + 1/7 (iv) m2 - √2m + 2 (v) P⁻² + 1

Answer 1

1 3 4 r polynomials and the rest r not polynomials.

2 no. is not polynomial coz it is getting divided.
5 no. is not because it has negative degree.



hope it helped u.

Answer 2

1 - cubic polynomial with variable "x"

2- it is not a polynomial because in polynomial there can not be algebraic expression in denominator.

3- it is a quadratic polynomial having " z" as variable.

4- it is also a quadratic polynomial with variable "m ".

5- it is not polynomial because polynomial can not have negative exponent .

hence, expression (1), (3),(4) are polynomial, and expression (2) and (5) are not polynomials'
algebraic expressions.
