Factorise: 2a +6b -3(a+3b)2

1.	Factorise: 2a +6b -3(a+3b)2
Answer» 2(a+3b) – 3(a+3b)² Now by taking (a+3b) as a common factor for the above equation we get, 2(a+3b) – 3(a+3b)² = (a+3b) (2 – 3(a+3b)) = (a+3b) (2- 3a -9b)

Answer»

2(a+3b) – 3(a+3b)²

Now by taking (a+3b) as a common factor for the above equation we get,

2(a+3b) – 3(a+3b)²

= (a+3b) (2 – 3(a+3b))

= (a+3b) (2- 3a -9b)
