Detailed Solution

The given polynomial is,

9992 − 992

We use the concept of algebraic identities to solve the given polynomial.
So,
We can simplify it as,

9992 − 992 = 999 − 99 999 + 99 a + b a − b = a 2 − b 2

⇒ 9992 − 992 = 900 × 1098

⇒ 9992 − 992 = 988200

Thus, the value of

9992 − 992

after simplifying it, is 988200
Hence, option 1 is the correct option.
