The expression is NOT a polynomial because the last variable term has a negative power of -3
How to determine why the expression is NOT a polynomial?
The expression is given as:
4/5x^3 - 2 + 8/x^3
As a general rule,
Polynomials are represented as:
ax^n +...........+b
This means that the least power of a polynomial term is 0 and each of the powers are non-negative integers
In 4/5x^3 - 2 + 8/x^3, the last term has a negative power of -3
Hence, the expression is NOT a polynomial because the last variable term has a negative power of -3
