Question

Write the solution set of the equation x²+x-2=0 in roster form.​

Answer 1

Answer:

x=-2;x=1

Step-by-step explanation:

x^2+x-2=0

x^2+2x-1x-2=0

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

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

☆x=-2 ;x=1

Answer 2

Answer:

Step-by-step explanation:

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}
