Q. 4

Classify the following polynomials based on their degree.

i. 3x2 + 2x + 1

ii. 4x3 – 1

iii. y + 3

iv. y2 – 4

v. 4x3

vi. 2x

Answer :

i. 3x2 + 2x +1


Since, the highest degree of polynomial is 2


It is a quadratic polynomial.


ii. 4x3 – 1


Since, the highest degree of polynomial is 3.


It is a cubic polynomial.


iii. y + 3


Since, the highest degree of polynomial is 1


It is a linear polynomial


iv. y2 – 4


Since, the highest degree of polynomial is 2


It is a quadratic polynomial.


v. 4x3


Since, the highest degree of polynomial is 3.


It is a cubic polynomial.


vi. 2x


Since, the highest degree of polynomial is 1


It is a linear polynomial
