Question

Write the solution set of the equation x^2+x-2=0 in roster form​

Answer 1

$\huge \underline \mathbb \red {ANSWER}$

The given equation can be written as :

$(x - 1)(x + 2) = 0 \\ \\ i.e. \: \: \: x = 1 \\ \: \: \: \: \: \: \: \: x = - 2$

Therefore, the solution set of the given equation can be written in roster form as { 1, - 2}

Answer 2

Answer:

Answer:

Step-by-step explanation:x2+x-2=0 here we are doing sum and product method so after doing it we would get x2+2x-1x-2 then it would become x(x+2)-1(x+2)then we will get it as (x-1)(x+2)where x=1 and x=-2then answer is {1,-2}
