Option 2,4,6 are correct.

Step-by-step explanation:

To find : Which polynomials are in standard form?

Solution :

A polynomial is in standard form when its term of highest degree is first, its term of 2nd highest is 2nd and so on.

Now we check all,

1)

As y degree is 1 so it goes to last.

No, it is not standard form.

2)

Yes, it is standard form as all of them degree is 3.

3)

As first term degree is 2 and last two term degree is 4 so first term goes to last.

No, it is not standard form.

4)

Yes, it is standard form as all of them degree is 4.

5)

As third term degree is 2 and last term degree is 3 so third term goes to last.

No, it is not standard form.

6)

Yes, it is standard form as all of them degree is 4.

Therefore, option 2,4,6 are correct.
