Question

The solution set of x^2+ 2 =0 is

Answer 1

Answer:

Answer: The solution set of the equation x2 + x - 2 = 0 is {1, -2} in roster form.

Let us see how we can solve this quadratic equation.

Explanation:

We have the equation, x2 + x - 2 = 0.

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

x2 + 2x - x - 2 = 0

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

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

So, x = -2 or x = 1

Thus, the solution set of the equation x2 + x - 2 = 0 in roster form is {1, -2}.

Answer 2

Example:-

We have the equation, x²+ x - 2 = 0.

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

x2 + 2x - x - 2 = 0

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

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

So, x = -2 or x = 1

Thus, the solution set of the equation x2 + x - 2 = 0 in roster form is {1, -2}.
