16-24ab-16a^2-9b^2 Помогите пожалуйта

Answer 1

$\tt 16-24ab-16a^2-9b^2=16-(16a^2+24ab+9b^2)=\\\\=4^2-(4a+3b)^2=(4-(4a+3b))(4+4a+3b)=\\\\=(4-4a-3b)(4+4a+3b)$

Answer 2

16 - 24 ab - 16a² - 9b² = -(16a²+24ab+9b² - 16) = -((4a)² + 2 * 4a*3b + (3b)² - 16 )=

= -((4a+3b)² - 16) = -((4a+3b)² - 4²) = -(4a+3b-4)(4a+3b+4) = (4-4a-3b)(4a+3b+4)
