Which option correctly writes the polynomial \\(8-3x+2x^2\\) in descending powers of x?
Answer and explanation
Correct answer: \\(2x^2-3x+8\\)
In descending order, the term with the highest power of x is written first, followed by terms with decreasing powers. The powers here are 2, 1, and 0, so the correct form is \\(2x^2-3x+8\\). Options B and C incorrectly change the sign of the x-term, while D changes signs and does not preserve the polynomial. Exam tip: identify each term’s power before arranging the terms from greatest to least.
