Answer:
Step-by-step explanation:
1) a² - b² = (a + b)(a- b)
2) a³ + b³ = a³ + 3a²b + 3ab² + b³
3) a³ - b³ = a³ - 3a²b + 3ab² - b³
5) x⁴ - 36 = (x²)² - 6² = (x² + 6) (x² - 6)
6)64c³ + 1 = (4c)³ + 1³ = (4c)³ + 3(4c)²(1) + 3(4c)(1)³ + 1³
= 64c³ + 3(16c²) + 12c +1
= 64c³ + 48c² +12c + 1
7) k³ - 27 = k³- 3³ = (k + 3)(k - 3)
Answer:
