# Which of the following is a polynomial?(i) 2x + (ii) + x2 (iii) y2 + y-3 (iv) 3 + 7

(i) On solving the equations,

After simplifying the equation, one of the term has a negative (-2) exponent.

So, following the ideal pattern of a polynomial, is not a polynomial.

(ii) On solving the equations,

After simplifying the equation, as it has a positive (2) exponent.

So, following the ideal pattern of a polynomial, is a polynomial.

(iii) On solving the equations,

After simplifying the equation, as the one of the term has a negative (-3) exponent.

So, following the ideal pattern of a polynomial, is not a polynomial.

(iv) On solving the equations,

After simplifying the equation, as the expression has a degree of .

So, following the ideal pattern of a polynomial, is not a polynomial.
