Question

A? http://prntscr.com/alr8fl

Answer 1

A polynomial can have:

constants (like 3, -20, or ½)
variables (like x and y)
exponents (like the 2 in y2), but only 0, 1, 2, 3, ... etc are allowed

Answer 2

In mathematics, a polynomial is an expression consisting of variables and coefficients which only employs the operations of addition, subtraction, multiplication, and non-negative integer exponents. An example of a polynomial of a single variable x is x2 − 4x + 7. An example in three variables is x3 + 2xyz2 − yz + 1.... from Google! :D

Answer 3

All these choices pretty much look the same though.. How would I be able to tell which is not a polynomial from these choices..?

Answer 4

The square root ones I think you can take out! :D

Answer 5

Alright, awesome. That leaves B, is it B?

Answer 6

I believe soo..I could be wrong..

Answer 7

@rebeccaxhawaii What do you think?

Answer 8

Option B is not correct. It has a variable x in a denominator.

Answer 9

Examples

Answer 10

Somebody said to take out the square root options. That is not correct unless there is an x variable under the square root.

It is okay if the number 6 is under a radical.

Answer 11

Okay, I know it's not a or b now, it has to be C or D, but they are basically the same.
Is it C?

Answer 12

Look at the options again. Square root of 6 is okay but square root of x is not.

Answer 13

Yes. x - sqrt(6)

Answer 14

Thank you! @Directrix
