Given :-
- (5x - 3y)(25x² + 15xy + 9y²)
Solution :-
Apply identity : a³ - b³ = (a - b)(a² + ab + b²)
→ (5x - 3y)(25x² + 15xy + 9y²)
→ (5x - 3y)[(5x)² + 5x*3y + (3y)²]
→ (5x)³ - (3y)³
→ 125x³ - 27y³
Extra Information
- (a + b)³ = a³ + b³ + 3ab(a + b)
- (a - b)³ = a³ - b³ - 3ab(a - b)
- a² - b² = (a + b)(a - b)
- (a + b)² = a² + b² + 2ab
- (a - b)² = a² + b² - 2ab
