Factorise : 2ab2 - Aby + 2cby - Cy2

Factorise : 2ab² - aby + 2cby - cy²

Sum

2ab² - aby + 2cby - cy²

= 2b (ab + cy) - y (ab + cy)

= (ab + cy) (2b - y)

Factorise by the grouping method : a² + b - ab - a

Factorise : - x²y - x + 3xy + 3

Factorise : a³ - a² - ab + a + b - 1

factorise: a² + 5a + 6

factorise: a² − 3a − 40

factorise: x(3x + 14) + 8

Factorise the following by grouping the terms:
8(2a + b)² - 8a -4b

Factorise the following by grouping the terms:
2m³ - 5n² - 5m²n + 2mn

Factorise the following by grouping the terms:
9x³ + 6x²y² - 4y³ - 6xy

Factorise the following by grouping the terms:

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