Объяснение:
1) a²+2ab+b²-p² = (a+b)²-p²
2) a²-2ab+b²-k² = (a-b)²-k²
3) m²-n²-8m+16 = m²-8m+16-n² = (m-4)²-n²
4) b²-a²-12a - 36 = b-(a+6)²
5) 1-25a²+10ab-b² = 1-(5a+b)²
6) 9-m²+n² -6n = -m²+n²-6n+9 = -m²+(n-3)²
7) 4a²+b²-9c²-4ab = 4a²-4ab+b²-9c² = (2a-b)-9c²
8) 9a²+4b²-4c²+12ab = 9a²+12ab+4b²-4c² = (3a+2b) - 4c²
