Vedclass · Answer

(A) An expression is a polynomial if the exponents of the variable are non-negative integers. In the expression $\sqrt{3} x^{2}+\pi x-9$,the variable is $x$. The exponents of $x$ are $2$ and $1$,which are non-negative integers. Therefore,it is a polynomial. Since the expression contains only one variable $x$,it is a polynomial in one variable.

Which of the following expressions is a polynomial? State the reason. If an expression is a polynomial,state whether it is a polynomial in one variable or not: $\sqrt{3} x^{2}+\pi x-9$
