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
A. \(3+2\sqrt{3}\)
Concept
(x-2=\(\sqrt{3}\)2=3).
Why this answer is correct
\(2x=2\sqrt{3}\), so \(x^2+2x=3+2\sqrt{3}\).
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।
