Question :-

Solve the following.

• (a - c)(a + c)(a²+b²)

Solution :-

= (a-c)(a+c)(a²+b²)

= a (a + c) + c (a + c) (a²+b²)

= a² + c² + ac + c² + a² + b²

Add the like terms.

Some useful identities :-

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• (a + b)³ = a³ + b³ + 3ab (a + b)
• (a - b)³ = a³ - b³ - 3ab (a - b)
