Explanation opens after your attempt
A. \(-\sqrt{3}\)
Concept
\(2x^2-x-6=2\cdot3-\sqrt{3}-6=-\sqrt{3}\). Simplify \(x^2\) first in exams.
Why this answer is correct
The correct answer is A. \(-\sqrt{3}\). \(2x^2-x-6=2\cdot3-\sqrt{3}-6=-\sqrt{3}\). Simplify \(x^2\) first in exams.
Exam Tip
\(2x^2-x-6=2\cdot3-\sqrt{3}-6=-\sqrt{3}\) है। परीक्षा में \(x^2\) को पहले सरल करें।
