♣ Qᴜᴇꜱᴛɪᴏɴ :
- Simplify : (a + b) (a - b) (a² + b²)
★═════════════════★
♣ ᴀɴꜱᴡᴇʀ :
(a + b) (a - b) (a² + b²) = a⁴ - b⁴
★═════════════════★
♣ ᴄᴀʟᴄᴜʟᴀᴛɪᴏɴꜱ :
(a + b) (a - b) (a² + b²)
We know (a + b) (a - b) = a² - b²
(a + b) (a - b) (a² + b²)
= (a² - b²)(a² + b²)
= a²(a² + b²) - b²(a² + b²)
= a⁴ + a²b² - b²a²+ b⁴
= a⁴ + a²b² - a²b² + b⁴
= a⁴ + b⁴
