Which polynomial is in standard form?

A) 3x6 + 4x4 + 6x5 + 7x2 - 8x

B) 5x6 + 3x4 + 6x3 + 5x2 - 2x

C) 5 + 3x + 6x2 + 5x3 - 3x4

D) 6x + 3x4 + 4x6 + 5x8 + 2

B. 5x6 + 3x4 + 6x3 + 5x2 - 2x

Step-by-step explanation:

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

So, in our case, we can take a look at the exponents in each row.

A would be 6, 4, 5,2, and 1. That would not be correct since it is not from greatest to least. With the 6 being the highest and 5th being the 3rd highest.

C would be 0, 1, 2, 3, 4. That would not be correct since that is from least to greatest.

D. would be 1, 4, 6, 8 and 0. That again would not be correct since its numbers are going from least to greatest to least.
