Answer 2

Step-by-step explanation:

let one number be x,

then another number is (-2-x)

and their products are -99

(x) × (-2-x) = -99

-2x - x^2 = -99

x^2 + 2x = 99

x^2 + 2x - 99 =0

x^2 + 11x - 9x - 99 =0

x(x+11) -9(x+11) =0

(x+11) (x-9) = 0

x = - 11 or x = 9

if x = -11 , another number became 9

and if x= 9 , another number became -11
