Question

Which algebraic expression is a polynomial? 4x2 – 3x + StartFraction 2 Over x EndFraction –6x3 + x2 – StartRoot 5 EndRoot 8x2 + StartRoot x EndRoot –2x4 + StartFraction 3 Over 2 x EndFraction

Answer 1

Answer:

The Answer is B

Step-by-step explanation:

Answer 2

Answer:

B.$-6x^3+x^2-\sqrt5$

Step-by-step explanation:

Polynomial of one variable:It is that expression in which power of each variable in the given should be a whole number.The highest power of variable is called degree of polynomial.

Power of  variable in given terms cannot be negative or fraction.

A.$4x^2-3x+\frac{2}{x}$

It can be write as

$4x^2-3x+2x^{-1}$

By definition of polynomial of one variable , it is not a polynomial.

B.$-6x^3+x^2-\sqrt5$

By definition of polynomial of one variable , it is a  polynomial.

C.$8x^2+\sqrt{x}$

By definition of polynomial of one variable, it is not  a polynomial.

D.$-2x^4+\frac{3}{2x}$

By definition of polynomial of one variable,it is not  a polynomial.

Hence, option B is true.
