Answer :
Now,
81 - (x - 7)²
= 9² - (x - 7)²
= (9 + x - 7) {9 - (x - 7)},
using the identity
a² - b² = (a + b) (a - b)
= (2 + x) (9 - x + 7)
= (2 + x) (16 - x),
which is the required factorization.

Now,
81 - (x - 7)²
= 9² - (x - 7)²
= (9 + x - 7) {9 - (x - 7)},
using the identity
a² - b² = (a + b) (a - b)
= (2 + x) (9 - x + 7)
= (2 + x) (16 - x),
