Which polynomial is written in standard form with descending powers?
Answer and explanation
Correct answer: 5x³ + 2x - 1
A polynomial is in standard form when its terms are arranged from the greatest exponent of the variable to the least, usually placing the constant term last. In option B, the powers are 3, 1, and 0, which decrease from left to right: 5x³ + 2x - 1. Option A is not descending, C is ascending overall, and D uses increasing powers.
