Which polynomial is in standard form? a) 2x5 − 3x3 − 6x2 + 7x + 9 b) 2x2 − 3x3 − 6x4 + 9x + 11 c) 8x − 3x3 + 6x2 + 9x5 + 10 d) 8 − 3x + 6x2 + 9x3 + 11x4

A

Step-by-step explanation:

A polynomial is in standard form when its term of highest degree is first, its term of 2nd of next highest degree is 2nd etc..

Check all options:

A. Polynomial is in standard form, because degrees are in descending order.

B.  Polynomial is not in standard form, because degrees are not in descending order. The standard form of this polynomial is

C. Polynomial is not in standard form, because degrees are not in descending order. The standard form of this polynomial is

D. Polynomial is not in standard form, because degrees are in ascending order. The standard form of this polynomial is
