# Write the solution set of the equation x^{2} + x - 2 = 0 in roster form.

We will solve this quadratic equation.

## Answer: The solution set of the equation x^{2 }+ x - 2 = 0 is {1, -2} in roster form.

Let us see how we can solve this quadratic equation.

**Explanation:**

We have the equation x^{2} + x - 2 = 0

We have to factorise it to get the solution in roster form.

x^{2} + 2x - x - 2 = 0

x (x + 2) -1 (x + 2) = 0

(x + 2) (x - 1) = 0

So, x = -2 or x = 1
