drakerton 5) p² - 4q² = (p-2q)(p+2q)

6) -36a² + 12ab - b². Сначала разделим на -1:
-36a² + 12ab - b² / -1 = 36a² - 12ab + b² = (6a-b)² = (6a-b)(6a-b)

7) 8y³ - 125x³ = (2y-5x)(4y²+10yx+25x²)

8) 8ab - ax - pb + px = a(8b-x) - p(b-x)

9) x³ - 3x² + 2x - 6 = (x-3)(x²+2)

10) (a+6)² - 25 = (a+6)² - 5² = (a+6-5)(a+6+5) = (a+1)(a+11)
