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

Factorise : a³ - a² - ab + a + b - 1

Factorise : 2ab² - aby + 2cby - cy²

factorise: x² - 10xy + 24y²

factorise: 12(a + b)² - (a+ b) - 35

Factorise the following by grouping the terms:
15x² + 7y - 3x - 35xy

Factorise the following by grouping the terms:
x(x - 4)- x + 4

Factorise the following by grouping the terms:
4abx² + 49aby² + 14xy(a² + b²)

Factorise the following by grouping the terms:
p²x² + (px² + 1)x + p

Factorise the following by grouping the terms:
x² - (p + q)x + pq
