Answer 2

Answer:

796404

Step-by-step explanation:

798 can be written as 1000 - 202

998 can be written as 1000 - 2

(1000-202) * (1000-2)

By identity (ex+a) (x+b) = x² + x(a+b)+ab

(1000)²+ 1000[(-202) + (-2)] + (-202)(-2)

1000000 + 1000(-204) + 404

1000000 + 204000 + 404

796000+404

796404
