Which expressions are polynomials?

select each correct answer.

4x+x√−1

35x²

7x^7−x^−5

x/5+2

Here, 4x+x√−1 cannot be a polynomial as variable is in root
7x^7−x^−5 cannot be a polynomial as exponent is in negative

35x² is a monomial here (Polynomial with 1 degree)

In short, Your Answer would be Option B and D
