Quizplus · Accepted Answer

To solve the quadratic inequality $x^2 - 5x - 6 \leq 0$, first factor the quadratic expression. The factors are $(x + 1)(x - 6) \leq 0$. The roots of the equation are $x = -1$ and $x = 6$. The inequality is satisfied between these two roots, including the roots themselves, hence the solution is $[ - 1,6 ]$.
