Question

please solve this problem fast and give reason for them​

Answer 1

Answer:

(i), (ii),(iii),(v) are polynomial and (iv) is not a polynomial.

it is because a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non- negative integer exponents of variables.

since, (iv) has negative exponet of variable.

y+2/y=(y²+2)/y =(y²+2)$y^{-1}$=y+2$y^{-1}$. so, it is not a polynomial

Answer 2

Step-by-step explanation:

(i), (ii),(iii),(v) are polynomial and (iv) is not a polynomial.

it is because a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non- negative integer exponents of variables.

since, (iv) has negative exponet of variable.

since, (iv) has negative exponet of variable.y+2/y=(y²+2)/y =(y²+2)y^{-1}y−1 =y+2y^{-1}y−1 . so, it is not a polynomial
