Which option writes a polynomial in (x) in standard form?

Answer and explanation

Correct answer: x^5+3x^2-2x+7

In the standard form of a polynomial, terms are arranged in descending powers of the variable. In option B, the powers are 5, 2, 1, and 0: \(x^5+3x^2-2x+7\). Hence, it is in standard form. In option A, \(x^5\) appears after lower-degree terms, so the terms are not in descending order. Exam tip: Check that powers go from the highest power down to the constant term.
