This question asks you to find the roots of a quadratic equation by factorisation.

‹ ›

\( \text{Find the roots of } x^2 - 12x + 27 = 0 \)

Select all correct options:

Check pairs of numbers whose product is 27 and sum is -12. Solve each factor separately.

Factor the quadratic \(x^2 - 12x + 27\) as \((x-3)(x-9) = 0\). The roots satisfy \(x - 3 = 0\) or \(x - 9 = 0\).
