Question

factorise 3-12(a-b)^2

Answer 1

Answer:

3 ( 1 - 2a + 2b ) ( 1 + 2a - 2b )

Step-by-step explanation:

3 - 12(a - b)²

= 3 [ 1 - 4(a - b)² ]                      [ common factor 3 ]

= 3 ( 1² - (2(a - b) )² )

= 3 ( 1 - 2(a - b) ) ( 1 + 2(a - b) )          [ difference of squares ]

= 3 ( 1 - 2a + 2b ) ( 1 + 2a - 2b )
