Question

factorise 2a + 6b -3 (a+3b)^2

Answer 1

2(a+3b)-3(a+3b)^2
(a+3b)[2-3(a+3b)]
(a+3b)[2-3a-9b)

Answer 2

Answer:

Factors of 2a+6b-3(a+3b)²=

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

Explanation:

Factorising 2a+6b-3(a+3b)²

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

= (a+3b)[2-3(a+3b)]

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

Therefore,

2a+6b-3(a+3b)²

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