Answer:
The polynomials are,
Explanation:
The polynomials are those which are of the form,
ax^n + bx^n-1 + ... px^2 + qx+ r
Now, The degree of polynomials cannot be less than zero,
Keeping this in mind, we have the following poylnomials,
15x^3,
option 2 has -1 power with x so it is not a polynomial
2x^2+5x-14 (degree 2)
x/8 + 13 (degree 1)
x^2/5 -2x+3
