WebApr 4, 2024 · We have to evaluate our number using this identity. So we can say (200-2) is the same as (a-b) so we simply put a as 200 and b as 2 in the given identity to evaluate. By putting the values we get, ( 200 − 2) 2 = 200 2 − 2 × 200 × 2 + 2 2 Now simplify the term that is on the right hand side, i.e. R.H.S= 200 2 − 2 × 200 × 2 + 2 2 =40000-800+4 =39196 WebQuestion Bank, Mock Tests, Exam Papers.

We have the identity: a² - b² = (a - b) (a + b) Here a = 271 and b = 29. ∴ 271² - 29² = (271 - 29) (271 + 29) = 242 × 300 = 72600 (ii) 291 × 306. We can write 291 × 306 as (300 - 9) (300 + 6) Using the identity (x + a) (x + b) = x² + (a ... gaslighting comments
