Question

The roots of the quadratic equation \( ax^2 - bx - c = 0 \) are:

• A. \( \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)
• B. \( \frac{b \pm \sqrt{b^2 + 4ac}}{2a} \)
• C. \( \frac{-b \pm \sqrt{b^2 + 4ac}}{2a} \)
• D. \( \frac{b \pm \sqrt{b^2 - 4ac}}{2a} \)

Hint:

For a quadratic equation \( ax^2 + bx + c = 0 \), the roots are given by: \[ x = \frac{b \pm \sqrt{b^2 + 4ac}}{2a}. \]

Answer 1

The Correct Option is B

The general quadratic equation is: \[ ax^2 + bx + c = 0. \] Using the quadratic formula: \[ x = \frac{b \pm \sqrt{b^2 + 4ac}}{2a}. \]
