Which is the correct formula to find roots of \(ax^2+bx+c=0\) by quadratic formula?
Explanation opens after your attempt
A. \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)
Concept
The quadratic formula is \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\). In exams, identifying (a), (b), and (c) correctly is most important.
Why this answer is correct
The correct answer is A. \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\). The quadratic formula is \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\). In exams, identifying (a), (b), and (c) correctly is most important.
Exam Tip
द्विघात सूत्र \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\) है। परीक्षा में (a), (b), (c) को सही पहचानना सबसे जरूरी है।
