यदि (p(x)=x-2-8x+10) है, तो इसके शून्यक कौन से हैं?
If (p(x)=x-2-8x+10), what are its zeroes?
Explanation opens after your attempt
Correct Answer
A. \(4+\sqrt{6}\) और \(4-\sqrt{6}\)\(4+\sqrt{6}\) and \(4-\sqrt{6}\)
Concept
By the formula, the zeroes are \(\frac{8\pm\sqrt{64-40}}{2}=4\pm\sqrt{6}\). Simplify the discriminant first.
Why this answer is correct
The correct answer is A. \(4+\sqrt{6}\) और \(4-\sqrt{6}\) / \(4+\sqrt{6}\) and \(4-\sqrt{6}\). By the formula, the zeroes are \(\frac{8\pm\sqrt{64-40}}{2}=4\pm\sqrt{6}\). Simplify the discriminant first.
Exam Tip
सूत्र से शून्यक \(\frac{8\pm\sqrt{64-40}}{2}=4\pm\sqrt{6}\) हैं। पहले विविक्तकर सरल करें।
