# Which of the following is a polynomial '? Find its zeroes.

(i) x^{2} ++ 2 (ii) x + (iii) 4 —x^{2}

Answer :

In the above expressions, only the thirdone has the positive power unlike others.

∴ It is the only polynomial.

Equating the expression with 0,

x^{2} = 16

∴ x = ±4

The zeroes of the polynomial are 4 & -4.
