Question

If \( x^2 + 2x - 5 = 0 \), then the values of \( x \) are

• A. \( 2, 2, -4 \)
• B. \( -2, 2, 4 \)
• C. \( -3, 2, 5 \)
• D. \( -2, -1, 3 \)

Hint:

To solve quadratic equations, use the quadratic formula: \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \).

Answer 1

The Correct Option is B

Step 1: Solving the quadratic equation.
The given quadratic equation is \( x^2 + 2x - 5 = 0 \). Using the quadratic formula, we find the values of \( x \) as \( x = -2, 2, 4 \).

Step 2: Conclusion.
The correct values of \( x \) are \( -2, 2, 4 \), corresponding to option (2).
