Step 1
Polynomials are algebraic expressions that consist of variables and coefficients.
An example of a polynomial with one variable is;
[tex]x^2+x-12[/tex]
All the exponents in the algebraic expression of a polynomial must be non-negative integers in order for the algebraic expression to be a polynomial. As a general rule of thumb if an algebraic expression has a radical in it then it isn’t a polynomial.
The given question is;
[tex]x^2+3x^{\frac{1}{2}}[/tex]
Answer;
[tex]No[/tex]
This is because of the radical in the power of the x with a coefficient of 3.
