Step-by-step explanation:

Answer 2

Answer:

$9 {(a - 2)}^{2} - 16 {(a + 2)}^{2} \\ = 9( {a}^{2} - 4a + 4) - 16( {a}^{2} + 4a + 4) \\ = 9{a}^{2} - 36{a} + 36 - 16{a}^{2} - 64a - 64 \\ = - 7{a}^{2} - 100{a} - 28$

=−(7a²+100a+28)

=−(7a²+2a+98a+28)

=−[a(7a+2)+14(7a+2)]

=−(a+14)(7a+2)

This is your answer hope it helps to you☺️
