State whether the given algebraic expression is polynomial? Justify.
$2 - 5 \sqrt{x}$

An algebraic expression in which the variable involved have only non-negative integral powers is called a polynomial.
Here,
$2 - 5 \sqrt{x}$ is not a polynomial
Because the second term $- 5 x^{\frac{1}{2}}$ is a term with an exponent which is not a non-negative integer
