Answer 1

a) 9p² - (q - 3p)² = 9p² - (q² - 6pq + 9p²) = 9p² - q² + 6pq - 9p² =

= - q² + 6pq

b) 2(a - 2)(a + 2) = 2(a² - 4) = 2a² - 8

c) (b - 5)(b + 5)(b² + 25) = (b² - 25)(b² + 25) = b⁴ - 625

Answer 2

Объяснение:

а) 9р²–(q–3p)²= 9p²–(q²–6pq+9p²)= 9p²–q²+6pq–9p²= –q²+6pq

b) 2(a–2)(a+2)= 2(a²–4)= 2a²–8

c) (b–5)(b+5)(b²+25)= (b²–25)(b²+25)= b⁴–625
