If (p(x)=x-2-8x+13), what are its zeroes?
Explanation opens after your attempt
Correct Answer
A. \(4+\sqrt{3}\) और \(4-\sqrt{3}\)\(4+\sqrt{3}\) and \(4-\sqrt{3}\)
Concept
Using the quadratic formula \(x=\frac{8\pm\sqrt{64-52}}{2}=4\pm\sqrt{3}\). In exams simplify the discriminant.
Why this answer is correct
The correct answer is A. \(4+\sqrt{3}\) और \(4-\sqrt{3}\) / \(4+\sqrt{3}\) and \(4-\sqrt{3}\). Using the quadratic formula \(x=\frac{8\pm\sqrt{64-52}}{2}=4\pm\sqrt{3}\). In exams simplify the discriminant.
Exam Tip
द्विघात सूत्र से \(x=\frac{8\pm\sqrt{64-52}}{2}=4\pm\sqrt{3}\) मिलता है। परीक्षा में विविक्तकर को सरल करें।
