Q. 24.8( 12 Votes )

Determine the degree of each of the following polynomials:

(i) 2x – 1

(ii) –10

(iii) x3 – 9x + 3x5

(iv) y3 (1 – y4)

Answer :

(i) 2x – 1


The degree of polynomial 2x – 1 is one (1) because the highest power ( maximum exponent) of the variable x in the given expression is 1


(ii) –10


The degree of polynomial – 10 x0 is zero(0) because the highest power( maximum exponent) of the variable x in the given expression is zero (0).


(iii) x3 – 9x + 3x5


The degree of polynomial x3 – 9x + 3x5 is five (5) because the highest power( maximum exponent) of the variable x in the given expression is 5.


(iv) y3 (1 – y4)


The degree of polynomial y3 (1 – y4) is seven (7) because the highest power (maximum exponent) of the variable x in the given expression is 7


y3 (1 – y4 ) = y3 – y7
