Question

Which algebraic expression is a polynomial?

Answer 1

Which algebraic expression is a polynomial?

–6x3 + x2 – StartRoot 5 EndRoot

Explanation:

just did the test on edg.

Answer 2

B.
`-6x^3+x^2+√(5)`

Explanation:

For an algebraic expression to be a polynomial it must have:

1)Variable

2)Constants

3) Exponents of variables which has to be whole number.

These can be combined by math operations except by division of variable

A.
`4x^2-3x+(2)/(x)`

Not a polynomial the last term is a division by variable. This disqualifies it to be a polynomial.

B.
`-6x^3+x^2+√(5)`

It is a polynomial as it has variables with positive exponents and a constant term.

C.
`8x^2+√(x)`

Not a polynomial the last term[
`\sqrt x= x^{(1)/(2)}`] has a variable with exponent which is not a whole number. This disqualifies it to be a polynomial.

D.
`-2x^4+(3)/(2x)`

Not a polynomial the last term is a division by variable. This disqualifies it to be a polynomial.
