Answer 1

Step-by-step explanation:

Question:- (1002)×(998)

we can write 1002 as = (1000+2)

and also we can write 998 as = (1000-2)

so, the question will become= (1000+2)×(1000-2)

so, using the identity (a+b) × (a-b) = a²-b²

so option c is correct

Answer 2

Answer:

(C) (a+b)(a-b) =  $a^{2} - b^{2}$

Step-by-step explanation:

(a+b)(a-b) =  $a^{2} - b^{2}$

1002 × 998 = (1000 + 2)(1000 - 2)

= $1000^{2} - 2^{2}$

=1000000-4

=999996
