Explanation opens after your attempt
Correct Answer

A. \(3x^2+5xy+y^2\)

Step 1

Concept

Combining \(x^2\), (xy), and \(y^2\) terms separately gives \(3x^2+5xy+y^2\). Do not mix different variable parts.

Step 2

Why this answer is correct

The correct answer is A. \(3x^2+5xy+y^2\). Combining \(x^2\), (xy), and \(y^2\) terms separately gives \(3x^2+5xy+y^2\). Do not mix different variable parts.

Step 3

Exam Tip

\(x^2\), (xy), और \(y^2\) पदों को अलग जोड़ने पर \(3x^2+5xy+y^2\) मिलता है। अलग चर भागों को न मिलाएं।
