Write the solution set of the equation $x^2 + x – 2 = 0$ in roster form. |
{1, – 2} {1, 2} {-1, – 2} {2, – 2} |
{1, – 2} |
The correct answer is Option (1) → {1, – 2} The given equation can be written as (x – 1) (x + 2) = 0, i. e., x = 1, – 2 Therefore, the solution set of the given equation can be written in roster form as {1, – 2}. |
