Q6 of 168 Page 7

Which of the following is a polynomial? Find its degree and the zeroes.

2 - x2

The highest power is 2, so the degree is also 2.


Equating the expression with 0,




x2 = 4


∴ x = ±2


Yes, the above expression is a polynomial, as it has no negative powers in any of the terms and its zeroes are 2 & -2.
