Factorise : xy - ay - ax + a² + bx - ab

Sum

xy - ay - ax + a² + bx - ab

= y (x - a) - a (x - a) + b (x - a)

= (x - a) (y - a + b)

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise : 6a² - 3a²b - bc² + 2c²

Factorise : (a² − b²) c + (b² − c²)a

Factorise : ax + 2bx + 3cx - 3a - 6b - 9c

Factorise : 2ab²c - 2a + 3b³c - 3b - 4b²c² + 4c

factorise: x² - x - 72

factorise: a² - 23a -108

factorise: x(3x + 14) + 8

Factorise the following by grouping the terms:
9 + 3xy + x²y + 3x

Factorise the following by grouping the terms:

`"p"^2 + (1)/"p"^2 - 2 - 5"p" + (5)/"p"`
