(Y-6)*(y+6)

(a-4) *(a^2+4a+16)

(8-b-1)*(8+b+1)=(7-b)*(9+b)

(4y+3x)*(4y+3x)

9a^2+6ab+b^2-12ab=(3a-b)*(3a-b)

Надеюсь все понятно:)

Verified answer

1. y² - 36 = (y-6)(y+6)

2. a³ - 64 = (a-4)(a²+4a+16)

3. 64 - (b+1)² = (8-b-1)(8+b+1) = (7-b)(9+b)

4. 16y²+24xy+9x² = (4y+3x)²

5. (3a+b)² - 12ab = 9a² + 6ab + b² - 12ab = 9a² - 6ab + b² = (3a-b)²
