I think expressions containing x in denominator as well as Square root part will not count in as Polynomials..

anonymous · Answer

is it A,B,&E?

anonymous · Answer

E??

In E, x is in square root form..

anonymous · Answer

In general any expression can be considered a polynomial if it is built from variables and constants using only addition, subtraction, multiplication, and raising expressions to whole number powers

anonymous · Answer

Then @waterineyes is right

anonymous · Answer

A, B..

What about C part??

anonymous · Answer

C is also in square root form you said "Square root part will not count in as Polynomials"

anonymous · Answer

the answer is C because the max power is above 2 i.e$$x^{3}$$

anonymous · Answer

Hey, there is difference between "Square Root" and "Square".. . no??

anonymous · Answer

better definition just googling:In mathematics, a polynomial is an expression of finite length constructed from variables (also called indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and non-negative integer exponents.

anonymous · Answer

well thanks you guys ! wish I could give you all medals

anonymous · Answer

In C are you seeing this thing anywhere $\sqrt{..}$ ??

anonymous · Answer

no

anonymous · Answer

We are not finished yet..
C is also a polynomial..

Now what about F??

anonymous · Answer

Is x in denominator or square root form there in F??

anonymous · Answer

yes because its also a square!

anonymous · Answer

Yep, it is also a polynomial..

So:
A, B, C and F win here...

anonymous · Answer

the correct answers were actually A,C,F

anonymous · Answer

Oh wait that was 7 raised to negative x^2??

Oh really very sorry I thought that was $7x^2$ instead of $7x^{-2}$..

anonymous · Answer

I have not seen the - part clearly there..

Sorry, B is not..
