Question 1 of 1 2 Marks

For which value(s) of \( k \) will the equation \( x^2 - 6x + k = 0 \) have real and equal roots?

Official Marking Guideline Rationale:
Correct Answer: A. Correct! \( \Delta = (-6)^2 - 4(1)(k) = 36 - 4k = 0 \implies 4k = 36 \implies k = 9 \).
Marking Criteria:
• Correct calculation of k via discriminant → A or k = 9 (2 marks)
