Answer:(a² - 4b² - 9)(a² - 4b² + 9)
(a^4 - 8a²b² + 16b^4) - 81
= [(a²)² - 2.4a²b² + (4b²)²] - 9²
= (a² - 4b²)² - 9²
= (a² - 4b² - 9)(a² - 4b² + 9)
Step-by-step explanation:
Answer:
8x + 3
Step-by-step explanation:
The cost of 5 t-shirts and 3 skirts
= 5(x - 3) + 3(x + 6)
= 5x - 15 + 3x + 18
= (5x + 3x) + (-15 + 18)
= 8x + 3
