यदि \(x=\sqrt{3}\), तो \(x^2+2x\) किसके बराबर है?

If \(x=\sqrt{3}\), what is \(x^2+2x\) equal to?

Explanation opens after your attempt
Correct Answer

A. \(3+2\sqrt{3}\)

Step 1

Concept

(x-2=\(\sqrt{3}\)2=3).

Step 2

Why this answer is correct

\(2x=2\sqrt{3}\), so \(x^2+2x=3+2\sqrt{3}\).

Step 3

Exam Tip

Simplify the square and the product separately. चरण 1: (x-2=\(\sqrt{3}\)2=3)। चरण 2: \(2x=2\sqrt{3}\), इसलिए \(x^2+2x=3+2\sqrt{3}\)। चरण 3: वर्ग और गुणा को अलग-अलग सरल करें।
