This question involves solving a quadratic equation by factorisation where the roots have different signs.

‹ ›

\( \text{Solve: } x^2 - x - 6 = 0 \)

Choose one option:

Look carefully at the signs. Substitute roots back to verify they satisfy the equation.

Identify two numbers \(m\) and \(n\) such that \(m \times n = -6\) and \(m + n = -1\). Use them to factor the equation as \((x - 3)(x + 2) = 0\).
