Factorise by the grouping method: 16 (a + b)² - 4a - 4b

Factorise by the grouping method : a²x² + (ax² + 1) x + a

Factorise by the grouping method : (2a-b)² -10a + 5b

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise : a³ -a² +a -1

Factorise : 3a²b - 12a² - 9b + 36

factorise: a² + 5a + 6

factorise: a² - 23a + 42

factorise: b(c - d)² + a(d - c) + 3(c - d)

Factorise the following by grouping the terms:

`(1)/(25x^2) + 16x^2 + (8)/(5) - 12x - (3)/(5x)`
