Question

Classify the following as linear,quadratic or cubic polynomial:
1) x^3+5^x2+12.
2) 4^x2-49.
3) 5-3t.
4) 4y+11.
5) x^3+2^x2+3x+2.
6) 35^x2-16x-12​

Answer 1

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.
