Which polynomial is in standard form?
Romashka-Z-Leto [24]

Answer:

C

Step-by-step explanation:

Standard form is [ ax² + bx + c ]

The exponents and variables determine what comes first.  In [ 11x³ - 6x² + 5x ], we can see that the exponents are going from greatest to least and the last number doesn't have an exponent so it goes last. Essentially we can think of this as sorting each part from greatest to least using exponents -> variables -> number to determine that.

Best of Luck!
