Question

classify the following as linear, quadratic and cubic polynomials:
1)x^2+x
2)x-x^3
3)y+y^2+4
4)1+x
5)3t
6)r^2
7)7x^3
​

Answer 1

Answer:

Answer

(i) The highest degree of x

2

+x is 2, so it is a quadratic polynomials.

(ii) The highest degree of x−x

3

is 3, so it is a cubic polynomials.

(iii)The highest degree of y+y

2

+4 is 2, so it is a quadratic polynomials.

(iv) The highest degree of x in (1+x) is 1, so it is a linear polynomials.

(v)The highest degree of t in 3t is 1, so it is a linear polynomials.

(vi)The highest degree of r

2

is 2, so it is a quadratic polynomials.

(vii)The highest degree of x in 7x

3

is 3, so it is a cubic polynomials.
