90000-16

89984

Answer 2

$\huge{\underline{\underline{\blue{\bf{Solution:}}}}}$

→ Identity used in this Question :-

(a+b)(a-b) = a² - b²

→ 304 ×296

→ (300+4) (300-4)

→ 300² - 4²

→ 90000 - 16

→ 89984

Some More Identities :-

→ (a+b)² = a² + 2ab +b²

→ (a-b)² = a² - 2ab + b²

→ (x+a) (x-b) = x² + (a+b)x + ab

→ (a+b+c) = a² + b² + c² + 2ab + 2bc + 2ca
