2a + 6b – 3(a + 3b)2 = 2(a + 3b){-3(a + 3b)2} = (a + 3b){2(-3a – 9b)} = (a + 3b)(2 – 3a – 9b) So, We get, 2a + 6b – 3(a + 3b)2 = (a + 3b)(2 – 3a – 9b)

Answer :

2a + 6b – 3(a + 3b)²

= 2(a + 3b){-3(a + 3b)²}

= (a + 3b){2(-3a – 9b)}

= (a + 3b)(2 – 3a – 9b)

So,

We get,

2a + 6b – 3(a + 3b)² = (a + 3b)(2 – 3a – 9b)
