Answer 1

Answer:

$12(a + b) - 24 {(a + b)}^{2} \\ \\ \\ = 12(a + b)(1 - 2a - 2b)$

$= 12a + 12b - 24( {a}^{2} + {b}^{2} + 2ab) \\ \\ \\ = 12a + 12b - 24 {a}^{2} - 24 {b}^{2} - 48ab$

Answer 2

Answer:

12(a+b)[1-2(a+b)]

Step-by-step explanation:

12(a+b)-24(a+b)²

= 12(a+b)[1-2(a+b)]

using formula

x² = x*x

(a+b)² = (a+b)(a+b)
