Write the solution set of the equation ${x^2} + x - 2 = 0$ in roster form.
Write the solution set of the equation ${x^2} + x - 2 = 0$ in roster form.
The given equation can be written as
$\left( {x - 1} \right)\left( {x - 2} \right) = 0,$ i.e., $x=1,-2 $
Therefore, the solution set of the given equation can be written in roster form as $\{ 1, - 2\} $
