Question

The zeroes of the polynomial \( x^2 - 11 \) are:

• A. \( 11, -11 \)
• B. \( 11, -\sqrt{11} \)
• C. \( \sqrt{11}, -\sqrt{11} \)
• D. \( \sqrt{11}, -11 \)

Hint:

To find the roots of \( x^2 - c = 0 \), take the square root: \[ x = \pm \sqrt{c}. \]

Answer 1

The Correct Option is C

Step 1: Setting the polynomial to zero:
\[ x^2 - 11 = 0. \] Step 2: Solving for \( x \):
\[ x^2 = 11 \quad \Rightarrow \quad x = \pm\sqrt{11}. \]
