Correct Answer

B. (4)

Step 1

Concept

Multiplication gives \(x^5+2x^4-x^3-2x^2\), and \(x^5\) cancels. The remaining highest power is (4).

Step 2

Why this answer is correct

The correct answer is B. (4). Multiplication gives \(x^5+2x^4-x^3-2x^2\), and \(x^5\) cancels. The remaining highest power is (4).

Step 3

Exam Tip

गुणन से \(x^5+2x^4-x^3-2x^2\) मिलता है और \(x^5\) कटता है। बची सबसे बड़ी घात (4) है।
