● Evaluation using identities ●
Using identity : - a² - b² = (a + b)(a - b)
(176)² - (24)²
= (176 + 24)(176 - 24)
= 200 × 152
= 30400
Using identity : - a² - b² = (a + b)(a - b)
(176)² - (24)²
= (176 + 24)(176 - 24)
= 200 × 152
= 30400

Evalution by identity
(α)²-(b)²= (α+b)(α-b)
=(176)² - (24)² = (176+24)(176-24)
=(200)(152)
=200 x 152
=30400
Hope u like it..!!
