Yes you are correct. 

Polynomials have more than 2 terms. 

Monomial -1
Binomial-2
Polynomial- 3+

anonymous · Answer

1) $$3x+\frac{ 4 }{ 3 }x^3-7$$

2) $$-5x^3+x-\frac{ 3 }{ x }$$

3) $$x^3\sqrt{5}+x-3$$

4) $$25x^2-x^3+x^5$$

Which ones do you think are polynomials?

anonymous · Answer

i know they all have more than one term BUT would the radical make it not a polynomial

marissalovescats · Answer

Yes it would make it not

anonymous · Answer

the only one which i believe is a polynomial is the last one

marissalovescats · Answer

The last one yes. 

But there is one more

anonymous · Answer

would it be the first one

anonymous · Answer

because the second one has 3/x
