Write the degree of each of the following polynomials:

(i) 2x3 + 5x2 - 7

(ii)

(iii)

(iv)

(v)

(vi) 5

(vii)

Answer :

(i) 2x3 + 5x2 - 7


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 3.


Therefore degree of the polynomial is 3.


(ii)


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 2.


Therefore degree of the polynomial is 2.


(iii)


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 2.


Therefore degree of the polynomial is 2.


(iv)


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 7.


Therefore degree of the polynomial is 7.


(v)


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 3.


Therefore degree of the polynomial is 3.


(vi) 5


Degre is the highest power of the variable of a polynomial. In the given polynomial there is no variable term.


Therefore degree of the polynomial is 0.


(vii)


Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 4.


Therefore degree of the polynomial is 4.
